Weight of Aerated Concrete in 1 m3: Bulk and Specific Weight
Aerated concrete is a building material made from cement with the addition of sand and lime. Clean materials that do not contain harmful substances are used in its production. Thanks to a special production technology, aerated concrete has such characteristics as resistance to fire, rust, rot, frost and water.

| D400 | 400 |
| D500 | 500 |
| D600 | 600 |
| D700 | 700 |

Popular aerated concrete block sizes: 200x200x600, 250x200x600, 280x200x600, 300x200x600, 360x200x600, 400x200x600, 500x200x600, 75x200x600, 100x200x600, 120x200x600, 150x200x600 mm.
In construction, the first thing calculated is how much aerated concrete weighs, that is, the weight of one cubic meter of aerated concrete, because this characteristic determines the specifics of its use and application. There are two concepts for calculating weight: the bulk weight of aerated concrete and the specific weight of aerated concrete. Bulk weight is the total weight of the material, while specific weight is the weight without taking gas inclusions and air into account.
For the calculation, it is necessary to find out how many blocks are in one cubic meter of aerated concrete. This is done using the volume formula: height, width and length of the block are multiplied. Let us consider an example of an aerated concrete block with the following parameters: height - 250 mm, width - 400 mm, length - 625 mm. Converting these parameters into meters gives 0,25; 0,4 and 0,625 m. Now, to calculate the volume of one block, we multiply the parameters and get 0,0625 m3. Knowing this value, we can calculate the number of blocks by dividing one by the volume of one block. As a result, we get 16, meaning that one cubic meter contains exactly this number of blocks.
Determining the Specific Weight of Aerated Concrete by Grade, Density and Block Size
To calculate the weight of one cubic meter of aerated concrete, it is necessary to multiply the block volume calculated above, the block density and the number of blocks. Density is indicated by the material grade. For example, a D500 block has a density of 500 kg/m3, while D900 has 900 kg/m3.
Returning to our example, let us calculate the weight of one block. For the example, take grade D500 density: multiply 500 by 0,0625 and get the weight of one aerated concrete block, which is 31,25 kg. Then multiply by the number of blocks: 31,25x16, and get the weight of 1 m3 of aerated concrete, 500 kg.
Frequently Asked Questions
Can the density of aerated concrete in 1 m3 be used for precise calculations?
The density and weight values for aerated concrete in 1 m3 in this article are reference values. They are suitable for preliminary estimates, but design, construction, production and other critical calculations should be checked against standards, material datasheets or measurement results.
Why can the actual weight of aerated concrete in 1 m3 differ from the table?
The actual weight of aerated concrete in 1 m3 depends on composition, moisture, temperature, porosity, fraction size, material grade and measurement conditions. Because of this, real values may differ from the average table data.
How do you calculate the mass of aerated concrete in 1 m3 from density?
For an approximate calculation, use the formula: mass = density × volume. If the density of aerated concrete in 1 m3 is given in kg/m³ and the volume is in m³, the result will be in kilograms.
