Many characteristics of foam concrete are available for everyone to study
Introduction  
Foam concrete is a kind of porous material, which is usually prepared into foam by mechanical method from the aqueous solution of foam agent, and then added to the slurry containing silica materials, calcareous materials, water and various admixtures, and then mixed, poured and cured
Because foam concrete contains a large number of closed pores, it has the following good physical and mechanical properties
fold
1
Lightweight  
The density of foam concrete is small, and the density grade is generally 300-1800kg/m3
The density of foam concrete is commonly used
Level 300-1200  Kg/m3, in recent years, the density is   160  Kg/m3 ultra light foam concrete 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

2
Good thermal insulation performance  
Because foam concrete contains a large number of closed small pores, it has good thermal performance, that is, good insulation
Thermal insulation performance, which ordinary concrete does not have
Generally, the density grade is 300-1200  The thermal conductivity of foam concrete in the range of 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

3
Good sound insulation and fire resistance  
Foam concrete is a porous material, so it is also a good sound insulation material, which can be used on the floors of buildings and highways
This material can be used as the sound insulation layer for the sound insulation panels of roads and the top floors of underground buildings
Foam concrete is an inorganic material and will not burn

Foam concrete  
  Foam concrete  
Therefore, it has good fire resistance
When used in buildings, it can improve the fire resistance of buildings

4
Good overall performance  
It can be cast on site and closely combined with the main works
fold
5
Low elasticity and good shock absorption  
The porosity of foam concrete makes it have low elastic modulus, which makes it have good absorption and
Dispersion
fold
6
Strong waterproof performance  
Cast in situ foam concrete has low water absorption, relatively independent closed bubbles and good integrity, which makes it have certain
Waterproof performance
7
Good durability   The service life is the same as that of the main project
fold
8
Convenient production and processing  
Foam concrete can not only be produced into various products in the factory, but also be constructed on site and cast into houses directly
Surface, floor and wall
9
Good environmental performance  
The raw materials required for foam concrete are cement and foaming agent
Most of the foaming agents are close to neutral and do not contain harmful substances such as benzene and formaldehyde
Quality, avoiding environmental pollution and fire hazards
fold
10
Convenient construction  
Just use the cement foaming machine to realize automatic operation, and pump to realize long-distance transportation with a vertical height of 200 meters,
The workload is 150-300 cubic meters / working day
fold
11
Other performance  
Foam concrete also has good pumpability during construction, high compressive strength (0
5-22
2mpa), and impact energy absorption
Good performance, large amount of industrial waste can be used, and the price is low

construction technology of foam concrete  
The construction of foam concrete is completed on site through a complete set of special equipment
The whole set of equipment is equipped with feeding, mixing, host and other systems
During construction, feeding, mixing, foaming are carried out on site, and are directly sent to the construction base level through the self-contained pumping system through the high-pressure transmission pipe
