Foam concrete application technology

                                                                                                                                                                                                                                                                                                      our It is a porous material formed by mixing, stirring, casting and curing in the slurry.

1 Main technical content

The foaming agent is fully mechanically foamed through the foaming system of the foaming machine, and the foam is evenly mixed with the cement slurry, and then through foaming It is a new type of lightweight insulation material containing a large number of closed pores formed by natural curing for cast-in-place construction or mold molding using the pumping system of the machine; foamed concrete is mixed with foaming agent, cement, fly ash, stone powder, etc. It is a double set of continuous-structured polymers that form an organic binder and contains uniform pores; it is a bubble-like thermal insulation material, and its outstanding feature is the formation of closed foam pores inside the concrete, making the concrete lightweight and thermally insulating.

2 Technical indicators

1) Lightweight

The density grade of foamed concrete is generally 300~1800kg/m3. The density grade of commonly used foamed concrete is 300~1200kg/m3. Due to the low density of foam concrete, the use of this material in internal and external walls, floors, floors, columns and other building structures of buildings can generally reduce the weight of the building by about 25%, and some can reach 30% of the total weight of the structure. %~40%. Moreover, for structural members, if foam concrete is used instead of ordinary concrete, the bearing capacity of the member can be improved. Therefore, the use of foamed concrete in construction projects has significant economic benefits.

2) Good thermal insulation performance

Because foamed concrete contains a large number of closed small pores, it has good thermal properties, that is, good thermal insulation performance. This It is something that ordinary concrete does not have. Generally, foamed concrete with a density level in the range of 300 to 1200kg/m3 has a thermal conductivity between 0.08 and 0.3w/(m·K), and its thermal resistance is about 10 to 20 times that of ordinary concrete. Using foamed concrete as building wall and roof materials has good energy-saving effects.

3) Good sound insulation and fire resistance

Foam concrete is a porous material, so it is also a good sound insulation material. This material can be used as a sound insulation layer on the top floors of buildings. Foam concrete is an inorganic material that does not burn and therefore has good fire resistance. When used in buildings, it can improve the fire resistance of buildings.

4) Good overall performance

Foam concrete can be poured on site for construction and is closely integrated with the main project.

5) Low elasticity and good shock absorption

The porosity of foamed concrete gives it a low elastic modulus, so that it has good absorption and dispersion of impact loads. .

6) Strong waterproof performance

Cast-in-situ foamed concrete has low water absorption, relatively independent closed bubbles and good integrity, which makes it have certain waterproof performance.

7) Good durability performance

Same as the life of the main project.

8) Convenient production and processing

Not only can foam concrete be produced into a variety of products in the factory, but it can also be constructed on-site and cast directly into roofs, floors and wall.

9) Good environmental performance

The raw materials required for foamed concrete are cement and foaming agent. The foaming agent is neutral and does not contain harmful substances such as benzene and formaldehyde, which avoids Environmental pollution and fire hazards.

10) Convenient construction

Only need to use the cement foaming machine to realize automatic operation, and can pump to achieve long-distance transportation with a vertical height of 200m, and the workload is 150~300m3/job day.

3 Scope of application

Suitable for roof insulation slope finding, ground insulation cushion, upturned beam foundation pit filling, wall pouring, etc.</p
