Hunan foam concrete

Performance comparison between foam concrete and ceramsite concrete  
Density  
The dry density of foam concrete ranges from 150 to 1600kg/m3, the dry density of ceramsite concrete ≥ 800kg/m3, and the dry density ranges from 400 to 800  kg/m3
Is the most commonly used density range of this kind of filling insulation material
In contrast, foam concrete has a larger selection range than ceramsite concrete,  
Insulation  
The thermal conductivity of foam concrete increases with the increase of dry density
The thermal conductivity of commonly used 400 ~ 800kg/m3 foam concrete is between 0
08 ~ 0
23w/m · K, while the dry density of ceramsite concrete is ≥ 800kg/m3, and the thermal conductivity is ≥ 0
23w/m · K
in terms of thermal insulation performance, foam concrete is far better than ceramsite concrete
Waterproof  
Although foam concrete is a high porosity material, due to its unique closed bubble structure, foam concrete has a low water absorption, usually ≤ 10%, while ceramsite concrete is mainly filled with a large amount of ceramsite, which reduces the density of ceramsite concrete, while ceramsite has a high water absorption, so foam concrete has better waterproof performance than ceramsite concrete

Homogeneous  
Foam concrete is a high flow cement-based foam mixture with good workability and integrity
Because the density of ceramsite concrete is small, it mixes with cement slurry, and the ceramsite floats up, resulting in serious stratification of ceramsite concrete, poor homogeneity of materials, and poor overall performance
Pumping  
Because foam concrete has no aggregate and high fluidity, all density foam concrete can be pumped, and both piston pump and screw pump can be used
Because ceramsite concrete contains a large amount of light aggregate, piston pump must be used, and the density of pumped ceramsite concrete must be ≥ 1000kg/m3
Therefore, ceramsite concrete has poor workability, while foam concrete is convenient and flexible

Venue  
Foam concrete can be pumped on site by mixing on site and pumped on site by factory mixing truck
It can be flexible according to the size of the construction site, and the equipment covers a small area
Ceramsite concrete can only be pumped on site by truck, which has high requirements for transportation and site
Manual  
Foam concrete is pumped by hose and self leveling, and the surface is easy to receive light
In many cases, ceramsite concrete requires manual material to transport ceramsite, and manual mixing on site consumes a lot of manpower

Economy  
The unit production cost of foam concrete is slightly lower than that of ceramsite concrete
On the surface, the price of foam concrete is equivalent to that of ceramsite concrete
However, due to the high consumption of human and material resources of ceramsite concrete, the cost of vehicle transportation depends on the distance to the construction site, and the additional unit cost is high
The comprehensive unit cost of foam concrete (cost per cubic meter) can be saved by 10% compared with that of ceramsite concrete, Therefore, foam concrete has better economy than ceramsite concrete
Compared with ceramsite concrete, foam concrete has the advantages of lighter weight, better heat preservation effect, better waterproof effect and better overall performance
In addition, foam concrete also has the excellent pumping performance and construction performance that ceramsite concrete does not have
It has low site requirements, small labor consumption, low unit cost, and saves money and energy
