Foam concrete, also known as foamed cement and lightweight concrete, is a new building energy-saving material with waste utilization, environmental protection, energy conservation, low cost and non combustibility
Light weight concrete (foam concrete) is a concrete product with a large number of small closed pores and equivalent strength, which is formed by introducing air, nitrogen, carbon dioxide, oxygen and other gases into the concrete slurry through chemical or physical means according to the application needs, and after reasonable curing and forming

Foam concrete is a new type of energy-saving and environment-friendly building material
Scholars at home and abroad have done a lot of research and development on it, making it widely used in wall materials, but it still has some defects, such as low strength, cracking, water absorption, etc
Therefore, to further expand its application field, we need to do further research in foaming agent, mix proportion, process flow, equipment, etc

It can be applied to retaining walls, construction of sports fields and track and field runways, sandwich components, composite wallboards, pipeline backfilling, lean concrete filling, roof slopes, support of tank footings, etc
However, there are some defects in its application, such as low strength, cracking, water absorption and so on, and its performance needs to be further improved
Light weight
The density of foam concrete is small, and the density grade is generally 300-1800kg/
Foam concrete m3, the density grade of common foam concrete is 300-1200 kg/m3, and ultra light foam concrete with density of 160 kg / m3 has also been applied in construction engineering
Due to the low density of foam concrete, the use of this material in the internal and external walls, floors, floors, columns and other building structures of buildings can generally reduce the self weight of buildings by about 25%, and some can reach 30% - 40% of the total weight of structures
Moreover, for structural members, if foam concrete is used instead of ordinary concrete, the bearing capacity of members can be improved
Therefore, the use of foam concrete in construction projects has significant economic benefits

Thermal insulation
Because foam concrete contains a large number of closed small pores, it has good thermal performance, that is, good thermal insulation performance, which ordinary concrete does not have
Generally, the thermal conductivity of foam concrete with density grade in the range of 300-1200 kg / m3 is between 0
08-0
3w/ (m · K), and the thermal resistance is about 10-20 times that of ordinary concrete
Using foam concrete as building wall and roof material has good energy-saving effect

Sound insulation and fire resistance
Foam concrete is a porous material, so it is also a good sound insulation material
It can be used as a sound insulation layer in the floors of buildings, sound insulation panels of highways, and the top floors of underground buildings
Foam concrete is an inorganic material, which will not burn, so it has good fire resistance
When used in buildings, it can improve the fire resistance of buildings

Overall performance
It can be cast on site and closely combined with the main works

Low elastic shock absorption
The porosity of foam concrete makes it have low elastic modulus, which makes it have good absorption and dispersion effect on impact load

characteristic
1
High heat resistance
As foam concrete is a cement inorganic material, its heat resistance can reach more than 500 ℃, and there is no thermal decomposition, so it has a longer service life and will not cause insulation failure

2
Green, non-toxic and harmless
Foam concrete does not contain any toxic ingredients, and foaming agents and various admixtures are not volatile and harmful
Material, conducive to the indoor environment

3
The strength is better than polystyrene foam
The compressive strength of polystyrene foam is only 0
02 ~ 0
03mpa, while the compressive strength of 200 ~ 300 kg /m3 foam concrete is 0
6 ~ 0
8 MPa, which is better

4
Lower use cost
The total cost of 200 ~ 300 kg /m3 foam concrete is only about 100 yuan, which has obvious economic advantages

5
The construction speed is fast
Foam concrete can be poured and leveled without laying one by one, and its construction speed is 1/3 faster than that of polystyrene foam plastic board

6
There is no joint, which reduces the heat loss caused by the joint

Foam concrete is widely used in energy-saving wall materials because of its good characteristics, and has also been applied in other aspects
At present, the applications of foam concrete in China are mainly cast-in-situ roof foam concrete insulation layer, foam concrete surface block, foam concrete lightweight wallboard, foam concrete compensation foundation

Foam concrete block (also known as autoclaved aerated block) is a kind of aerated concrete block
Its appearance quality, internal pore structure, service performance and so on are basically the same as autoclaved aerated concrete block
The internal pores of foam concrete block are not connected, while the internal pores of autoclaved aerated block are connected, so relatively speaking, foam concrete block has better thermal insulation performance, lower water seepage rate and better sound insulation effect!
The application of self insulating foam concrete block in non load-bearing walls overcomes the disadvantages of hollowing and cracking of aerated concrete block walls in the late stage, and can completely replace autoclaved aerated concrete block
It can give full play to the thermal insulation performance of thermal insulation materials and better achieve the thermal insulation effect of external walls
At the same time, it has the advantages of the same service life as buildings, wide application range, convenient construction, easy control of engineering quality, low price and so on, It has good promotion advantages
