The scope of application of foam cement
Pipeline backfill. Underground abandoned oil tanks, pipelines (built-in crude oil, chemicals), sewage pipes and other holes easily lead to fire or landslides, the use of foam concrete backfill can solve these troubles, the cost is also less. The density of foam concrete depends on the diameter of the pipe and the groundwater level, usually 600-1100kg / m? ;.
Construction of sports ground and athletics track. The use of strong drainage capacity of the infiltration of foam concrete as a light foundation, covered with gravel or artificial turf, as a sports field. The density of foam concrete is 800-900kg / m? Such stadiums can be hockey, soccer and tennis. Or in the foam concrete covered with a layer of 0.05m thick porous asphalt layer and plastic layer, can be used for track and field runway.
(3) for the sandwich components. In the prefabricated reinforced concrete components can be used as the core of foam concrete core, so that it has a good performance of light high-temperature insulation. Usually with a density of 400 - 600kg / m?; foam concrete.
Used as retaining wall. Mainly used as a port of the dyke. The use of foam concrete as a lightweight backfill material in the wall can reduce the vertical load and reduce the lateral load on the wall. This is because the foam concrete is a good adhesion of rigid body, it does not along the surrounding side of the wall to exert lateral pressure, settlement decreased, maintenance costs are reduced, thus saving a lot of expenses. Foam concrete can also be used to enhance the stability of the embankment slope, which replaces the soil with some of the slope, reducing the quality of the slope and reducing the stability of the slope.
