Brick or aerated concrete

Brick or aerated concrete – which is the better choice for construction work?

Everyone who wanted to build their own house had to choose building materials. Some advised buying bricks, others preferred aerated concrete elements, and others recommended a combination of both materials. Which is better – brick or aerated concrete – for the construction of a box? To find the correct answer to the question, it is necessary to study the differences in the characteristics and properties of these materials. The fact is that even professional masters do not have a common opinion. Each type has pros and cons that we recommend considering.

Properties of bricks Before choosing “brick-aerated concrete”, first consider the properties of the material. Environmentally friendly, strong enough and can be used for a long time. Brick buildings last at least 100 years. Reinforced concrete slabs are used as ceilings along such walls, making it possible to arrange large rooms or construct multi-storey buildings. There are two types of brick materials: silicate and ceramic. The first option is made from sand, lime and water. The manufacturing mold filled with raw materials is placed in an autoclave and fired while applying pressure.

The question is, “What material is it made of?” – One of the basics in any construction. Surely before you start building a cottage you wondered why choose brick if you are building your own house and concrete block if it is for sale? At least one of her visitors asked exactly this question (see article “Crete Block House or Brick House?”). This article was written to put the “i” in the question “What materials to build your own cottage: brick or concrete block?”

The main indicators for bricks and aerated concrete blocks

That is, whether the selected material is suitable for building a cottage in the area where you plan to live. In the Far North, he agrees that there is a difference between a two-story permanent home and a summer bungalow on the Mediterranean coast.

Let’s look at each indicator individually: how it affects the strength, stability and durability of the “box” of the house.

Compressive strength indicates the load that a material can withstand in kilograms per square centimeter. 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 a two-story cottage with a basement. Floor height – 2.5 meters. interfloor and attic floors – from reinforced concrete slabs.

In this case, bricks should be used when building external (bearing) walls. Because it is this material that can withstand the weight of load-bearing walls (which transfer the weight of the walls themselves and the weight of the floor between floors to the foundation). In this case, when using aerated concrete, you need to be prepared for the fact that the walls will not withstand the load of the ceiling and other structures. As a result, cracks may appear in the walls.

However, in this case, self-supporting walls (which only transfer their own weight to the foundation) or non-bearing walls (bulkheads) can be made of both bricks and aerated concrete.

Therefore, the greater the number of floors and the heavier the floors, the higher the compressive strength of the selected material should be.

I would like to emphasize here that it is impossible to “eyeball” the weight that the outer wall (and accordingly the material) will bear. Please contact your designer to ensure the correct choice of materials. Its role is to provide calculated data specifically about the loads on the walls of your home.
