充气混凝土和加气混凝土,都是轻质多孔建筑材料。加气混凝土,是掺入铝粉作加气剂制成的加气混凝土。充气混凝土,采取的物理方法充气,它和加气混凝土一样,可以制成砌块和板材,根据充气混凝土的容重,其抗压强度可为20—24公斤/平方厘米,抗拉强度为抗压强度的20％。充气混凝土有以下优点: 1.生产不用铝粉。因而相应地节约了能源。例如,生产20万立方米加气混凝土, Inflatable concrete and aerated concrete are light porous building materials. Aerated concrete is aerated concrete made by adding aluminum powder as an air-entraining agent. Inflatable concrete, inflated with physical methods, can be made into blocks and plates like aerated concrete. According to the bulk density of aerated concrete, the compressive strength can be 20-24 kg/cm2, and the tensile strength is compressive. 20% of strength. Inflatable concrete has the following advantages: 1. Production without aluminum powder. As a result, energy is saved accordingly. For example, producing 200,000 cubic meters of aerated concrete,
