Foam concrete classification

Foam concrete is a lightweight, heat-insulating, heat-insulating, fire-resistant, sound-insulating and frost-resistant concrete material. The slurry can be self-leveling, self-compacting, and has good construction ease. It is easy to pump and level, has good compatibility with almost all other building materials, and its strength can be adjusted.
Classification of Foam Concrete
(1) According to the composition of cementing materials
                According to the composition of cementing materials, it can be divided into cement foam concrete, magnesite foam concrete, gypsum foam concrete, and pozzolanic cementing material foam concrete. ?
(2) According to filling types
According to the types of main filling materials used, it can be divided into dozens of types. Such as fly ash foam concrete, coal gangue foam concrete, slag foam concrete, tailings sand foam concrete, straw powder foam concrete, etc. ?
(3) According to density grade
The density grade of foam concrete is the same as that of traditional air-entrained concrete. It is generally divided into 6 grades, namely: 300kg/m3, 400kg/m3, 500kg/m3, 600kg /m3, 700kg/m3, 800kg/m3 6 grades, of which 500kg/m3 and 600kg/mm3 are the main grades, and other grades are supplementary. The 600kg/m3 grade products are mainly used for load-bearing and insulation; the 500kg/m3 grade products are also used for load-bearing and thermal insulation; the 400kg/m3 grade and below are generally used for thermal insulation; the 700kg/m3 and above grades are generally used for load-bearing. ?
(4) Classification according to foaming method
Since there are many foaming methods, foam concrete should also be classified according to this. Currently it is mainly divided into two categories. One is foamed concrete; the other is aerated concrete, and aerated concrete has few practical applications.
(5) According to the use function
According to the use function, foam concrete can be divided into thermal insulation type, thermal insulation structural type and structural type.
(6) According to production technology
According to production technology, foam concrete is divided into cast-in-place concrete and foam concrete products.
(7) According to application fields
By application fields, foam concrete is currently divided into: foam concrete for housing construction (roofs, walls, walls, floor heating and other building parts products or cast-in-place), gardens Foam concrete (rockeries, garden ceramsite, floating objects on water, lightweight garden decorations, etc.), engineering foam concrete (backfilling of mines and other abandoned underground projects, compensation foundations, frost-resistant foundations, etc.), industrial foam concrete (industrial pipeline insulation, Industrial furnace insulation, chemical filtration, etc.).
(8) According to the maintenance method
Some companies classify foam concrete according to the maintenance method. There are three types of this classification, namely natural curing foam concrete, steam curing foam concrete, and steam curing foam concrete.
(9) According to pore diameter
Foam concrete with different pore sizes has great differences in its properties and uses. Therefore, for ease of use, foam concrete is classified according to pore size. According to actual needs, it is generally divided into three categories, namely microporous foam concrete (3mm).</p
