我国社会主义建设初期,工业厂房和部分民用建筑多采用泡沫混凝土作隔热材料。随着建筑技术的发展,相继出现了膨胀蛭石、矿棉、加气硅酸盐、膨胀珍珠岩以及多孔塑料制品等,隔热材料品种不断增加。由于材料成本和施工保健等因素的影响,多孔塑料和矿棉的应用并不普遍。膨胀珍珠岩 In the early stage of socialist construction in China, foamed concrete was used as insulation material in industrial plants and some residential buildings. With the development of building technology, there has been the emergence of expanded vermiculite, mineral wool, air-entrained silicates, expanded perlite and porous plastic products. Due to factors such as material costs and construction health care, the use of porous plastics and mineral wool is not widespread. Expanded perlite
