Aerated concrete occupies a special place in modern construction due to its lightness and good thermal insulation properties. However, in addition to these advantages, an important factor is its strength, which is determined by a number of factors. The choice of suitable aerated concrete for construction according to this criterion plays an important role in ensuring the reliability and durability of structures.

What density to choose aerated concrete

The choice of the appropriate density of aerated concrete depends on the specific conditions of construction and the purpose of the structure. Here are some recommendations for selecting the material according to its brand:

• Low density (D400-D500). These grades of aerated concrete are suitable for the construction of internal partitions and small non-load bearing walls, where there are no high loads.
• Medium density (D600-D800). Aerated concrete blocks of this group are used in construction for load-bearing walls and interstorey ceilings in private houses.
• High density (D900-D1200): These grades of aerated concrete provide high strength and are used in the construction of apartment buildings and commercial facilities.

When selecting the grade of aerated concrete, it is important to consider the purpose of the structure, its loads, and the specifics of the area where construction will take place. It is also important to pay attention to local building codes and material strength requirements.

Strength index of aerated concrete

The ability of a material to resist bending is a critical aspect of building structures. Flexural strength determines the ability of aerated concrete to withstand loads acting on it along its length or width. This parameter is particularly important for structural elements that are subject to dynamic loads or mechanical stresses, such as beams, slabs and foundations.

The flexural strength of aerated concrete depends on its composition, density and structure. Higher strength grades of aerated concrete typically have greater resistance to bending, making them preferable for building more loaded structures. In general, this index allows engineers and builders to select appropriate materials and optimize structures to improve their reliability and durability.
