Classification of aerated concrete blocks
The sizes of the materials used determine how the design parameters of the building under construction are calculated:
- Degree of strength;
- Thermal insulation of the structure;
- The choice of the type of masonry of walls and partitions;
- As well as on the costs of transportation, storage and installation.
Bricks’ geometric dimensions will also affect their final cost.
The following determines the primary geometric parameters:
- Their width;
- In height;
- Length.
Kindly take note! The wall structure’s strength properties, sound insulation, and thermal insulation are all impacted by the width size. Consequently, material that is 10 or 15 cm thick is used for partitions and 30 cm thick material is primarily used for external walls.
The material’s height and length are chosen with ease of installation in mind, keeping in mind the overall dimensions of the walls. Production is governed by GOST 31360-2007.
- Standard parameters;
- Non-standard.
All of the producers of this product make regular gas blocks. Non-standard dimensions may be a trademark of a particular brand or produced in response to specific orders.
The following determine geometric parameters:
Material category
A category of aerated concrete bricks is assigned according to maximum deviations:
- I category;
- II category.
The following criteria are used to establish maximum deviations:
- Individual size;
- Geometric shape;
- General appearance.
Geometric parameters
Geometric dimension deviations are ascertained by:
- Length of the brick;
- Thickness;
- As well as height.
Deviations in shape
Parameters such as the following are used to evaluate deviations from the correct shape:
- Difference in diagonal lengths;
- Straightness of all brick edges.
Deviations in appearance
Gas blocks are evaluated visually for cracks, chips, and chip depth:
- Corners;
- Longitudinal and transverse ribs;
- Grooves and ridges – if any.
Shapes of aerated concrete blocks
Bricks are made based on shape:
- Smooth rectangular;
- Rectangular with pockets for gripping;
- With a groove – ridge system;
- U-shaped;
- Non-standard shapes.
Recesses and chamfers with figures can also be used to create gas blocks.
Application area
They are separated based on the application area:
- For erecting walls;
- Devices of lintels;
- Laying and fastening floor slabs;
- Construction of permanent formwork for the foundation.
When building walls, the sizes differ based on:
- Single-layer structure;
- Multi-layer structure.
The material can only be used as permanent formwork if the brick is protected from the elements by waterproofing.
Standard-sized aerated concrete blocks
The maximum parameters for standard aerated concrete materials are as follows:
- Length up to 62.5 cm;
- Width – 50 cm;
- Height – 50 cm.
Smooth aerated concrete blocks
- Load-bearing and self-supporting wall structures;
- Indoor partitions;
- Window and door lintels.
Materials for load-bearing and self-supporting external structures
Standard sizes – smooth and straight
- height 20 cm or 25 cm;
- 60 cm or 62.5 cm long.
Partition aerated concrete products
Slabs for lightweight partitions can be as thick as 15 cm.
Employed as
- Partitions inside the building;
- Installation of various communications.
Typically measuring 20 cm in height and 60 cm in length, they come in various thicknesses:
Lintels for openings
The standard height of 0.2 meters, the reduced length of 0.5 meters, and the thickness of lintel for window and door openings vary:
- B 25 cm;
- B 30 cm;
- B 36 cm;
- In 40 cm.
Groove-ridge system
Crucial! Because they are manufactured with unique grooves and ridges, aerated concrete bricks can be installed more quickly, precisely, and easily. With a lock system like this, you can level out the masonry and save a lot of adhesive money because the side surfaces of the products don’t always require glue.
This is only achievable with precisely the right geometry of aerated concrete components, with very little variation in size.
U-shaped products made of aerated concrete
This kind is employed:
- when installing lintels above windows and doors;
- laying floor slabs.
Their typical height is 25 cm, and their measurements are as follows:

- and in length – 0.5 m or 0.6 m.
A U-shaped component is frequently utilized as a lintel above apertures.
A reinforcing belt is made to support floor slabs along the top row of products.
It is required because
- More uniform distribution of the load from the floor slab;
- Strengthening the supporting structure of the wall.
The selection of U-shaped aerated concrete material parameters is based on design computations. The building’s perimeter is surrounded by blocks, the interior is reinforced, and concrete mortar is applied. The reinforced belt is used to lay floor slabs.
Non-standard geometric dimensions of aerated concrete products
Manufacturers typically deviate from the standard parameters for specific building projects.
When releasing product lines with a specific slope, this option is feasible.
On the building site, a traditional hacksaw is used to create non-standard elements. Aerated concrete products are simple to work with, making it possible to obtain blocks of any size—for instance, to neatly finish a row of masonry. The aerated concrete masonry dressing requires additional components as well.
Damaged blocks are typically used to create more elements. If a different product shape is required, creating bevels and notches by hand is a fairly simple process.
