国外大多数厂家主要生产蒸压加气混凝土制品和构件。生产泡沫混凝土较少。瑞典的伊通、西波列克斯公司采用现代化切、铣设备及其它设备来生产低容重、高强度的加气混凝土制品。伊通公司主要生产平均容重500—600公斤/米~3,相应强度4.5和5.5兆帕的加气混凝土。用波特兰水泥、石灰、磨细砂制备的加气混凝土的配比为水泥20%,石灰30%,水固比为0.6。石灰中 CaO 含量为80—95%,MgO 不低
Most foreign manufacturers mainly produce autoclaved aerated concrete products and components. There is less foam concrete production. The Ito and Spreeks companies in Sweden use modern cutting and milling equipment and other equipment to produce low-capacity, high-strength aerated concrete products. Yitong Company mainly produces aerated concrete with an average bulk density of 500-600 kg/m3 and corresponding strength of 4.5 and 5.5 MPa. The proportion of aerated concrete prepared with Portland cement, lime, ground sand is 20% of cement, 30% of lime, and the ratio of water to solid is 0.6. CaO content in lime is 80-95%, MgO is not low
