Cement Cement is the main source of fly ash aerated concrete block strength. It is aerated concrete provides the main calcareous materials. Suitable for production of fly ash aerated concrete block cement, primarily to cement varieties and labels both options. It should be the first choice in the production of ordinary portland cement 52.5. In general, Hainan Jia aerated concrete block density, to reduce production costs, should use 42.5 ordinary portland cement as well. Shenzhen Branch-Building Material Co., aerated concrete block is a lightweight porous, thermal insulation, good fire performance, can be nailed, sawed, planed and has a seismic capacity of new building materials. Temperature resistance aerated concrete temperature is below 600 ℃ Hainan Jia aerated concrete block investment, the compressive strength increased slightly, when the temperature at about 600 ℃, the compressive strength compressive strength approaching normal temperature, so As fire performance of aerated concrete building materials meet the state fire safety standards level.
