苏联的多孔混凝土包括加气混凝土(占90%)和泡沫混凝土(占10%)两种。现在,多孔混凝土制品和结构在墙体材料中占4%,在钢筋混凝土结构和构件中占1.5%,在保温材料中占8%。在一些经济区和共和国,多孔混凝土制品在墙体材料中的比重是很大的。多孔混凝土建筑结构是最经济的、消耗能量和材料较少的轻质结构。在居住和工业建筑物外墙中使用容重为700和600公斤/米~3的多孔混凝土板分别代替容重为1100和950公斤/米~3的陶粒混凝土板,可保证每平米4.5—5卢布的经济效益。折算费用降低17—26%。综合基建
Porous concrete in the Soviet Union consists of aerated concrete (90%) and foamed concrete (10%). Porous concrete products and structures now account for 4% of wall materials, 1.5% of reinforced concrete structures and components, and 8% of insulation materials. In some economic zones and republics, the proportion of porous concrete products in wall materials is large. Porous concrete structures are the most economical, lightweight structures that consume less energy and materials. The use of perforated concrete slabs with a bulk density of 700 and 600 kg/m~3 in the external walls of residential and industrial buildings instead of ceramsite concrete slabs with a bulk density of 1100 and 950 kg/m~3 can guarantee 4.5-5 rubles per square meter. The economic benefits. The conversion fee is reduced by 17-26%. Comprehensive infrastructure
