In the process of concrete mixing, the mixing method of admixture has a great influence on the effect of admixture. Admixtures can be used for almost all kinds of concrete, but suitable admixtures must be selected according to engineering needs, construction conditions and construction technology. Thermal insulation materials refer to materials or material composites that have significant resistance to heat flow. Lightweight foamed concrete, also known as foamed cement, is a lightweight porous concrete product made from foaming agent aqueous solution into foam, and then adding foam to the slurry made of cement-based cementitious materials, aggregates, admixtu The open-cell foam concrete is an excellent sound absorption material, while the closed-cell foam concrete is an excellent sound insulation material. Foam concrete contains a large number of closed pores, the air in the pores is a good adiabatic medium, which can cut off the heat exchange. Before construction, ensure that all kinds of instruments used during construction can operate normally, check their status and break the work, and the materials must be in place. Foamed concrete is a highly entrained sand cement with at least 20% air volume in the cured product. Foam concrete has a low density. In practical application, the density grade of ordinary foam concrete is 300 kg/m3~1200kg/m3. Foam concrete is a highly workable low-density material containing up to 80% air.
