In this article under aerated concrete we will understand the cellular concrete, which is obtained from a mixture of cement, sand, water and gas-forming additives that form bubbles in concrete, making the density and thermal conductivity of concrete lower.

By brick is meant a familiar, ceramic building material, produced by firing various clay mixtures.

Both ordinary brick and aerated concrete have a number of specific characteristics by which they can be compared. Among them:

1. weight;
2. compressive strength;
3. thermal conductivity;
4. frost resistance;
5. fire resistance;
6. vapor permeability;
7. moisture absorption.

Having information about the above indicators, you can already judge whether this material is suitable for you, taking into account the location and purpose of the future building. Therefore, we will describe each parameter in detail below.

Mass of material

The mass of individual fragments forms the mass of the walls, but it should be taken into account when choosing the type of foundation to be laid.

For these reasons brick walls require the presence of a more complex, and therefore more expensive foundation(mainly monolithic or tape), but aerated concrete walls in this regard are less demanding.

But, aerated concrete, unlike brick, has very weak bending strength, which means that the shrinkage of the foundation must be very well done.

A good foundation for aerated concrete should not shrink, and frost heaving should not move it. Therefore, great attention should be paid to the drainage of the foundation and backfilling of non-porous fillers (sand and gravel).

In principle, on good soils, a shallow foundation with an insulated blind area is suitable; for more complex soils, it is better to carry out soil geology.

In any case, the choice of one or another foundation depends on the severity of the entire building, such as soil, on the depth of freezing and on the level ground water. And the calculation of all this is a complicated matter, which is best left to specialists.

Geometry of gas blocks and bricks

Gas blocks are much larger and smoother than bricks, what conclusion can be drawn from this? And here's one: a gas-block box is built much faster. The seams between the gas blocks are about 2 mm, which minimizes heat loss through the seam. Note that each row of the gas block must be leveled with a grater so that the plane is perfect and the seam is uniform, this is very important. The rows of the gas block are leveled with a grater very quickly and simply, so do not be afraid of this.

Also, some rows of aerated concrete need to be reinforced. More details about reinforcement of aerated concrete masonry see our article.

Aerated concrete can be autoclaved and non-autoclaved, we will immediately say that autoclaved aerated concrete is better in all respects, including the geometry of the blocks, but autoclaved is more expensive. More details about differences between autoclaved and non-autoclaved aerated concrete Read our article at the link.

There are no such requirements for seams in brickwork. It is also worth noting that in a house made of aerated concrete, a monolithic reinforced concrete armored belt is required. And as you understand, the armored belt is a complex design that requires a lot of time and money. The time saved on the laying of aerated concrete will be somewhat taken away when installing the armored belt.

As you might guess, this parameter indicates what level of load the material can withstand; calculated in kilograms per 1 cm². The overall strength of the structure significantly depends on the compressive strength.

The higher the walls of the building, the heavier they are, and the load on the blocks (in compression) increases, and the requirements for compressive strength increase. Compressive strength is usually denoted by classes ( B0.5 to B60) and for aerated concrete this indicator can be in the range from B0.5 to B20.

For example, high-quality aerated concrete brand D500 compressive strength class equals B3.5 which corresponds to the load 46 kg/cm².

Table, compressive strength (aerated concrete)

Aerated concrete brand	Compressive strength class	Average strength ( kg/cm²)
D300 (300 kg/m³)	B0.75 - B1	10 - 15
D400	B1.5 - B2.5	25 -32
D500	B1.5 - B3.5	25 - 46
D600	B2 - B4	30 - 55
D700	B2 - B5	30 - 65
D800	B3.5 - B7.5	46 - 98
D900	B3.5 - B10	46 - 13
D1000	B7.5 - B12.5	98 - 164
D1100	B10 - B15	131 - 196
D1200	B15-B20	196 - 262

Brick also has its own marking for strength (from M50 before M300). For example, brand of brick M100 corresponds to the compressive strength class - B7.5 which corresponds to the load 100 kg/cm².

Thermal conductivity

The thermal conductivity coefficient indicates the ability of the material to conduct heat through itself. This indicator means the amount of heat that passes per hour through 1 m³ of material with a unit temperature difference on opposite surfaces. That is, the higher the coefficient, the worse the thermal insulation.

The photograph from the thermal imager shows what the surface temperature is in which areas, than brighter color, the worse the thermal insulation in that area.

Table of thermal conductivity of aerated concrete

Comparative graph of thermal conductivity of bricks and aerated concrete

So, the graph clearly shows the difference in thermal conductivity between various bricks and aerated concrete, for example, the thermal conductivity of aerated concrete D500 is 4-5 times lower than that of a red solid brick. But these are all laboratory figures, in fact, in masonry, the difference between the thermal conductivity changes somewhat, and the thermal conductivity will differ not by 4-5 times, but by only three.

The reason for this is the so-called bridges of cold ”, which refers to the layers of mortar between the parts of the masonry.

In the case of aerated concrete blocks, a special adhesive is used for thin joints, which reduces the heat loss of the structure, but still, the actual performance of aerated concrete masonry in terms of thermal conductivity is lower than those presented in the table above.

It is also worth noting that the thickness of the joints in aerated concrete masonry should be as small as possible, ideally (1-3 mm). Thick seams in aerated concrete reduce all its thermal advantages to a minimum.

Another factor that worsens thermal insulation is the humidity of the blocks, the higher the humidity, the worse. And aerated concrete is porous and therefore absorbs water well.

According to thermal engineering standards, warm brick walls should have a solid thickness (1 m), while for aerated concrete walls, a thickness of 0.3-0.5 m is enough. For the coldest regions, aerated concrete masonry may be required as much as 600 mm thick.

In general, the thicker the walls, the thinner the seams, and the less damp the wall is, the better the heat will be retained inside the room and the more you will save on heating your home.

We repeat that aerated concrete comes in different grades, ranging from D200 and ending D1200. The number in this case indicates the density of the material. The higher the density, the stronger the block, but at the same time its thermal insulation properties are worse.

Aerated concrete grades D200-D300 is used as a heat insulator, and blocks grade D400 and above are used as structural blocks for walls.

At present, the construction of brick walls with a thickness of under 1 m is a rarity, because it is too expensive both in terms of money, and in terms of the amount of time spent, and in terms of labor resources.

Most often, brick walls are erected in one and a half to two bricks with a thickness of 38-50 cm, and a much thicker layer is used for thermal insulation. thermal insulation materials than when laying aerated concrete walls.

Frost resistance

This indicator demonstrates the resistance of the wetted material when exposed to sub-zero temperatures. It shows how well a material can maintain its strength under repeated freezing and thawing.

Frost resistance is denoted by the letter "F", the number indicates the number of cycles that the material must withstand.

As a rule, brick has a much higher frost resistance coefficient than aerated concrete, that is, brick is a more frost-resistant material, and therefore more durable.

moisture absorption

The moisture absorption index indicates the ability of the material to absorb and retain moisture. The absorption of water negatively affects the strength of materials, and the thermal conductivity also increases.

Since aerated concrete blocks are able to absorb 4-5 times more moisture than bricks, the walls of the aerated concrete block must be additionally protected from water ingress, which, of course, is a minus for aerated concrete.

Moisture absorption testing was carried out by placing the blocks in a container of water. A day later, blocks and bricks were taken out and weighed. The difference between the initial and final mass was converted into a percentage.

For example, we took a cube of aerated concrete measuring 10X10 cm, its weight was 592 grams, which corresponds to the D600 brand. after 18 hours of soaking, the weight of the cube was 869 grams. That is, aerated concrete absorbed 277 grams of water, which is 47% of its original mass. Many manufacturers of aerated concrete write that the moisture absorption of their blocks is only 20%, but something is hard to believe in this after such testing.

Fire resistance of aerated concrete and brick

This parameter shows the resistance ability building materials with direct exposure to high temperatures from open flames. The degree of fire resistance depends on how long building structure will be able to stand until cracks appear and collapses occur during a fire.

In this regard, brick and aerated concrete do not have any special differences, since both materials are included in the first class of fire resistance (limit 2.5). Both types of materials are quite good when it comes to resisting fire.

Conclusion

Aerated concrete retains heat better, and it has better vapor permeability than brick. But the brick is several times stronger in compression and fracture. In terms of moisture resistance and frost resistance, brick also wins. It becomes clear that brick is more durable, and a brick house can last much longer.

But many of the shortcomings of aerated concrete will be removed by high-quality facade cladding, which will prevent the gas blocks from getting wet. Moreover, wet aerated concrete retains heat worse.

Aerated concrete blocks are large, as a result of which it is faster to build a box of them, and aerated concrete also has better geometry. But the seams between the blocks of aerated concrete must be very thin (1-3 mm), otherwise there will be large heat losses.

Also, in a house made of aerated concrete, a reinforced concrete armored belt is needed, and in brickwork it is not necessary.

Aerated concrete walls are very afraid of uneven shrinkage of the foundation and can crack. So it is desirable, under aerated concrete, to make a heavy and very high-quality foundation and additionally give it time to infuse so that the main shrinkage passes.

We have compiled a comparative graph of various indicators, in which the higher the column, the better.

In other words, there is no unambiguous solution to the problem of choosing between brick and aerated concrete, since both materials have their own advantages and disadvantages. When choosing, one should start, first of all, from the project of the future construction, since in some cases it will be much more efficient to use aerated concrete, while in others it may be better to use the good old brick.

But in the realities of the twenty-first century, when the price of electricity and other sources of heating is very high, we would choose 400 mm thick aerated concrete with subsequent cladding. This thickness is enough to provide good thermal insulation without using additional heaters.

In the case of brick, when laying 0.4 meters, you need to use about 10-15 cm of additional thermal insulation with foam, mineral wool or other materials. But, the brick is time-tested, and the buildings from it stand for a hundred years or more, this is due to the good frost resistance of the brick and high compressive strength.

Many builders and self-builders are concerned about the question, which house will be cheaper to build, from aerated concrete or brick? For the impatient, we note that the final price comparison table is at the bottom of the article. Well, we will analyze in detail all the stages of building walls.

In this article, we will consider prices for bricks, gas blocks, glue, mortar, fittings, work, and more. The tables will show approximate prices both in hryvnia and in rubles.

Calculations of the cost of materials and work on bricks

We looked at all prices for materials and work in Ukraine, and for conversion to Russian prices , we have multiplied the prices by three.

As can be seen from the tables, construction of walls from aerated concrete is cheaper, but do not forget that for a house made of aerated concrete it is necessary need armored belt, the cost of which is approximately 500 UAH. (1500 rubles) per linear meter.

An example of calculating the cost of the walls of a house 10 by 10 meters with a ceiling height of 2.5 meters.

The cost of an armored belt for 50 linear meters is from 15,000 to 30,000 UAH (60-90 thousand rubles)

The cost of walls (80 m2) of aerated concrete and brick

The cost of the walls, taking into account the armored belt (for aerated concrete)

We took average prices for materials and work, and as you can see, aerated concrete walls with a thickness of 300 mm cost about the same as brick walls of one and a half bricks.

Calculations on the cost of insulation would not hurt, but that's a completely different story)

Very often, if you have planned to build a house, you will have to face the moment of choosing the right building materials. The question may immediately arise, from what will it be better to build a house, and most importantly more profitable? Here it is worth considering two very common materials for the construction of buildings, namely brick and aerated concrete. Such materials have come to the construction market for a long time and are very popular among buyers. It is worth noting that in this text, by the term brick, we will mean hollow blocks that are produced by firing clay mixtures.

The comparison implies the presence of a second material, in this case, aerated concrete was chosen. A similar material is produced by mixing lime, sand, cement, as well as additional gaseous additives. The two materials mentioned above differ significantly from each other in many parameters, namely: thermal conductivity, resistance to low temperatures, fire resistance, moisture absorption by the material, as well as strength. Given all these characteristics, it will be much easier for you to give your preference to one or another building material.

Comparative characteristics

1. The most important parameter in construction is the mass of the wall being built. Based on this parameter, you will have to choose what the foundation of the building will be. In this case, comparing brick or aerated concrete, the second option wins, since a wall made of such material will be much lighter. Therefore, you can use an inexpensive but reliable strip foundation. For bricks, you will have to select a more reliable foundation model, since the house will turn out to be quite heavy, you will have to choose either a monolithic foundation or a tape one, but with a sufficient recess.

1. After that, it is worth paying attention to such a parameter as thermal conductivity. This term refers to the ability of a material to transfer heat. If you do not want to delve into the numbers, it is safe to say that aerated concrete blocks retain heat in the room much better. However, not everything is so simple here, if the brick wall is thicker, then the thermal conductivity will increase significantly. In addition, it is worth noting that for brick walls, in addition to high costs, it is best to additionally buy an adhesive solution that will save you from cold bridges.
2. Further, when comparing two materials, it is worth paying attention to what resistance to low temperatures the compared blocks have. In this case, the brick surpasses the aerated concrete almost twice. Since the second material, when wet, it can behave very negatively at extremely low temperatures. If you are building a house for many years, and plan to pass it on to your children, then without a doubt it is better to choose brick walls. In the case when such a step is not planned, you can choose a more affordable option for building walls from aerated concrete blocks.

1. In addition to all of the above, it is worth noting that a house built of brick has a significantly greater strength of the walls. It is because of this parameter that very often the use of aerated concrete is banned. Such blocks are forbidden to be used for the construction of houses whose height will be more than fourteen meters. However, for the construction of small cottages, such material has been widely used.
2. Next, you should pay attention to such a parameter as durability. In this case, it depends on the ability of the erected walls to absorb moisture. The life of the building is significantly reduced with an increase in this parameter. In this case, it is better to choose brick blocks that have excellent resistance to moisture.

For laying walls of aerated concrete, you will have to choose warm sunny weather, otherwise the house may become covered with fungus in the future. It is worth noting that the completed wall of aerated concrete blocks must be primed to provide reliable protection from moisture. In addition, a special paint will need to be applied over the primer, which will repel fumes.

1. Such a parameter as fire hazard is no different in this comparison. Both materials are environmentally friendly and meet all the necessary modern requirements.
2. In the case of moisture shrinkage, brickwork behaves calmly, but a house made of aerated concrete blocks may slightly decrease in size, which will later lead to cracks in individual blocks or in entire walls. Based on this, we can conclude that the brick behaves much better. In addition, it is worth adding that the aerated concrete block can behave excessively negatively in places of contact with dry heat, namely with the chimney.

1. In the end, it is worth paying attention to mechanical processing. It is immediately worth noting here that aerated concrete block lends itself much better to various processing than brick. But during the further operation of the building, it is worthwhile to mount a variety of cabinets to the wall carefully, since the material is quite fragile. Everyone should have heard about brick walls that they can easily withstand a lot of different cabinets and similar elements.

Further, completing the story about the parameters of the compared materials, we can add that there is another model of bricks that are produced using a different technology. In this case, we are talking about a warm brick, or, as I also call it, a porous brick. To build a house from such material became available not so long ago, because a kind of building element appeared no more than forty years ago. All the positive qualities of ordinary brick were embodied here, however, this material is much better, since higher thermal insulation qualities were added here. Now, if you pay attention to the above comparisons, brick looks significantly better than aerated concrete. The house, which will be made of such material, will not only last longer, but will also be much warmer.

Now you can list the most striking advantages from the use of such material, namely: there are no restrictions when conducting construction works, ecological purity of the material, and besides, convenience in work is added. Also, a warm brick included all the most positive qualities from ordinary fireclay. In addition to all of the above, it can be added that such a material has the properties of natural conditioning. As a result, the house from the inside will be filled with its favorable microclimate.

After that, it is worth paying a little attention to the prices of the materials described above. Here, without a doubt, the leading place is occupied by aerated concrete block, which is much cheaper than even ordinary brick. In this case, the cost of one cubic meter material, not one piece. As for warm brick, it will also cost less than ordinary brick, but the difference here will not be so significant.

Comparing two such materials, make right choice not so, a lot depends on financial capabilities. The environment in which you live is also taken into account. For dry areas, aerated concrete buildings will be noticeably better than brick houses.

Therefore, it is unequivocal to answer that it will be right to choose a brick or aerated concrete, no one will undertake it for you. Each of the materials is good enough for its use. Based on this, it is worth noting that the decision on which material to choose is up to you. But it should be taken only after all the recommendations and comparisons have been taken into account by you. But first, it is worth considering your financial capabilities, since brick house enough expensive pleasure although it will last much longer. However, there is a small nuance here, if all construction technologies are correctly observed, then houses made of aerated concrete blocks serve their owners for a long time, it is only necessary to maintain the facade coating in proper condition. It is also worth noting that you can use a combination. In this case, we are talking about building a house from aerated concrete, followed by lining the walls with bricks.

The question "What material to build from?" - one of the fundamental in any construction. Surely you, before starting to build a cottage, thought: why, if they are building a house for themselves, they choose bricks, and if they are for sale - concrete blocks? At least one of our visitors asked exactly this question (see article). In order to dot the “i” in the question “What material to build your own cottage from: brick or concrete blocks?”, This article was written.

Terminology

Aerated concrete house with decoration

In this article under brick we will understand ceramic hollow brick obtained by firing clays and their mixtures in a kiln.

Hollow ceramic brick

Under aerated concrete- a type of cellular concrete, which is obtained from a mixture of binder sand and water with gas-forming additives.

Aerated concrete of various sizes

Brick and aerated concrete have specific indicators that characterize these materials according to the following parameters (see Table 1):

• ultimate compressive strength;
• weight;
• thermal conductivity;
• frost resistance;
• water absorption;
• fire resistance.

Knowing these indicators, we can say whether the selected material will correspond to the functional purpose, geographical location and structural design of the building.

The main indicators of brick and aerated concrete block

That is, whether the material you have chosen is suitable for the construction of your cottage, in the area in which you plan to live. Agree that there is a difference between a two-story permanent home in the Far North and a summer bungalow on the Mediterranean coast.

Table 1. Characteristics of ceramic bricks and aerated concrete

Let's look at each indicator separately: how it affects the strength, stability and durability of the "box" of the house.

Compressive strength shows how much load the material can withstand in kilograms per 1 cm2. The compressive strength directly affects the structural strength of the "box" of the house.

Let's look at an example. Suppose you are planning to build two-storey cottage with basement. Floor height - 2.5m. Interfloor and attic floors - from reinforced concrete slabs.

In this case, you need to use bricks when building external (bearing) walls. Because it is this material that can withstand the weight of load-bearing walls (which transfer their own weight and the weight of interfloor floors to the foundation). If in this case you will use aerated concrete, then you must be prepared for the fact that the walls will not withstand the load of ceilings and other structures. As a result, cracks can go along the walls.

But self-supporting (transferring only their own weight to the foundation) or non-bearing (partitions) walls, in this case, can be made of both brick and aerated concrete.

So, the more floors and the heavier the floors, the higher the compressive strength of the selected material should be.

It is important to emphasize here that “estimate by eye” the weight that will be carried outer wall(and, accordingly, the material), you are unlikely to succeed. To be absolutely sure of the correct choice of material, contact your designer. Its mission is to give you calculated wall load data specific to your home .

Aerated concrete block house

Another important indicator is wall mass(kg). The type of foundation of your house depends on this indicator (the choice of the type of foundation largely depends on the weight that the walls and interfloor floors will transfer). As you can see (see Table 1), the mass of aerated concrete is almost 20 times less than brick. Therefore, the foundation for brick walls will be more complex and expensive (for example, slab foundation or), than under aerated concrete walls (for example,).

Coefficient of thermal conductivity The material shows the ability to transfer (conduct) heat (calculated indicator of the amount of heat passing through 1 m3 of a material sample in 1 hour at a temperature difference of 1 °C on opposite surfaces). The higher this indicator, the worse the thermal insulation properties of the material.

As can be seen from Table 1, the thermal conductivity of brick is almost 4 times higher than that of aerated concrete. That is why it is recommended to build brick walls 1 m thick, and aerated concrete walls - 0.5 m (in accordance with SNiP II-3-79 * "Construction heating engineering"). However, in modern construction, few people build walls of a meter thickness - this is expensive in terms of time, labor, and money. Therefore, in practice, when laying brick walls (usually 25 cm thick), more heat-insulating materials (inside and outside) are used than when building walls made of aerated concrete.

Brick-lined house

Water absorption coefficient indicates the ability of a material to absorb and retain water. Water absorption worsens the properties of the material, increases thermal conductivity and average density, and reduces strength.

Table 1 shows that aerated concrete absorbs moisture 1.5 times faster than brick. This means that aerated concrete walls require more protection - you will most likely have to clad the facade of the house.

The next indicator is frost resistance material. It shows the ability to maintain wet materials strength during repeated alternation of freezing and thawing. As you can see (see Table 1), this coefficient for brick is higher (on average), which indicates that, in terms of frost resistance, brick is a more durable material than aerated concrete. Therefore, aerated concrete requires additional insulation and insulation from temperature extremes.

Under fire resistance understand the ability of a material (structure) to resist high temperatures in a fire.

The degree of fire resistance shows how long (in hours) the structure will withstand before the occurrence of collapses, the appearance of through cracks or holes, and elevated temperatures.

Both brick and aerated concrete belong to the first class of fire resistance (in accordance with SNiP 2.01.02-85 * "Fire safety standards"). This means that the outer bearing walls, which are made of these materials, have a minimum fire resistance of 2.5 hours (for comparison: the load-bearing walls of a building made of wood have a minimum fire resistance of 30 minutes).

Aerated concrete house with decoration

Of course, the comparison of brick and aerated concrete will not be complete if we do not consider the cost of these materials and the time that will be spent on the construction of the "box".

Comparison of ceramic bricks and aerated concrete block according to their characteristics

Table 2. Characteristics of brick parameters and gas concrete block

Let's start with the required amount of materials.

The size of one brick is 65x120x250 mm.

The size of one concrete block is 200x200x600 mm.

When calculating, it turns out that when laying 1 m3 of a brick wall, 380 pieces will be used up, from aerated concrete - 27 blocks.

The average market value of 1,000 pieces of bricks is UAH 1,200.00. (1.2 UAH/piece), and 1 package of aerated concrete (1 package contains 42 blocks) is 762.00 UAH (18.00 UAH/piece).

That is, 1m3 brick walls will cost you on average UAH 456.00(380 pieces x 1.2 UAH / piece), from aerated concrete - 486.00 UAH.(27 blocks x UAH 18.00/piece).

Now calculate the cost of installation work. The cost of brickwork is 500-750.00 UAH. for 1 thousand pieces, and aerated concrete masonry - UAH 150-250.00. for 1m3.

That is, 1 m3 brickwork will cost you on average UAH 320.00, a aerated concrete masonry - 200.00 UAH.

Summing up, we get that the average cost 1 m3 of brick wall masonry will cost UAH 776.00, and aerated concrete - UAH 686.00.

Attention! We would like to draw your attention to the fact that the price of materials and the cost of construction work varies not only within the country, but also within the city (maybe even the district). Therefore, it will first be necessary to calculate the cost of building walls, taking into account your location. The preparation of the estimate, again, lies with the design organization to which you applied.

Go ahead. You need to bring the selected and purchased material to the object. And this is where the question arises: where (in what region and place) do you plan to build? Check in advance if there are sellers of the selected material in your area and how much money they charge for delivery. Because it may happen that by choosing aerated concrete (it seems to be cheaper!), The cost of delivering this material to the facility can cover all the savings on it.

Note: As a rule, depending on the region, the cost of materials and work for the construction of a "box" of a brick house is 15-30% higher than that of aerated concrete.

Private house

As for the time factor, as can be seen from Table 2, aerated concrete walls are erected 20% faster than brick walls. This speed of work is related to the volume and weight of the material. Brick is actually 13 times smaller than aerated concrete, and weighs 4 times more. Imagine that in order to lay 1 m3 of an aerated concrete wall, the master needs to lift and put 400 kg of material, and 1,800 kg of brick. In practice, this means that a “box” of brick can be “expelled” in 3-6 months, and a “box” of aerated concrete - in 1-3 months.

Finally, I would like to dwell on the following point: the power of habit. In fact, we have formed a strong belief that a house can only be made of brick. And we find a lot of evidence for this, for example, some ancient fortresses stood for several hundred centuries and are perfectly preserved. Tradition is a safe and proven path. However, do not forget that the 21st century is in the yard - the development of technology does not stand still. Modern technologies allow you to save time, money, etc. The main thing is that their use should not be a tribute to fashion, but be a sober and balanced decision.

As you can see, it is impossible to say which is better: brick or aerated concrete. You probably understand that the concepts of “better-worse”, “more expensive - cheaper” are quite relative. They are applicable when you already have finished project your house. In one case, it is possible to use only bricks, in the other - only aerated concrete, in the third - a combination of one and the other is possible.

I would like to remind you once again that before making a choice in favor of one or another material, your designer should certainly compare all the technical and economic indicators of materials with respect to the project of your house. Only after that, it will be possible to say with confidence that the selected material is suitable for the construction of your cottage.
