Foam concrete used as railway sound insulation tape

At present, the use of foam concrete as a railway sound insulation band has developed significantly. Because the performance of foam concrete itself has great advantages as a railway sound insulation belt:

Foam concrete machine for fuel tank building

1. Lightweight. The use of foam concrete as a load-bearing thermal insulation wall or roof insulation can greatly reduce the weight of the building structure, and reduce the size of beams and columns and other load-bearing members, thereby reducing the amount of engineering, shortening the construction period, and reducing the engineering cost. It can also be used to achieve structural High-rise; on the other hand, more and more foam concrete is used for road or bridge foundation replacement backfill, this is because the low self-weight of foam concrete can reduce the foundation settlement caused by excessive self-weight stress of the foundation, prevent road collapse, Pedestrian jumps and other phenomena occur.

2. Good thermal insulation. A large number of spherical closed micropores are evenly distributed inside the foam concrete, so it has excellent thermal insulation performance. The dry thermal conductivity of foam concrete can be as low as 0.06W / (m · K), while the dry thermal conductivity of ordinary cement concrete is 1.5W / (m · K). Therefore, the foamed concrete has excellent thermal performance and can effectively achieve the purpose of energy saving and emission reduction.

3. Reduce noise pollution. Since the foam concrete has a pore structure inside, it has a good sound absorption effect, which can effectively reduce noise pollution and improve the living environment.

4. Adjust the room temperature. The water content of the foam concrete can change with the change of the indoor environment and can be used to balance the indoor humidity to keep it in a dry or humid state continuously, thereby effectively adjusting the room temperature.

5. Superior seismic performance. Foam concrete has the advantage of being lightweight. Using it as a material to make the relevant components of the building structure can effectively reduce the foundation load and improve the seismic resistance. In addition, the foam concrete is a porous structure with a low elastic modulus, which has good absorption and Dispersion is an excellent energy-absorbing shock-absorbing material.
