苏联装配式钢筋混凝土构件,1970年的生产量为8400万立米,其中8%是轻质混凝土构件。目前,苏联每年生产1800万立米轻质混凝土,用于结构与保温等方面。轻质混凝土总量的70%是陶粒混凝土。苏联配制轻质混凝土所用的轻集料,有天然的和人造的两种,用量较大的是陶粒、膨胀珍珠岩、膨胀矿渣、多孔烧结料和 Soviet assembled reinforced concrete components, the production volume in 1970 was 84 million cubic meters, of which 8% were lightweight concrete components. At present, the Soviet Union produces 18 million cubic meters of lightweight concrete each year for structural and thermal insulation. 70% of the total weight of lightweight concrete is ceramsite concrete. The lightweight aggregates used by the Soviet Union for the preparation of lightweight concrete are natural and man-made. The larger amounts used are ceramsite, expanded perlite, expanded slag, porous frit and
