苏联硅酸盐砖的生产现状目前,苏联年产硅酸盐砖约143亿块(折合标准砖250×120×65毫米),约占全国墙体材料总量的16%。苏联共有180家硅酸盐砖厂,其中年产量在6000万块标准砖以下的工厂占40%,年产6000～9000万块的占30%,其余的为年产9000万块砖以上,其中有8个工厂年产2亿块砖以上。每千块标准砖,活性为65～66%的石灰的平均耗用量为452公斤;砂子用量为2.32米~3;热能耗用 Production of Soviet Silicate Bricks At present, the Soviet Union produces about 14.3 billion silicate bricks (equivalent to standard bricks of 250 x 120 x 65 mm), accounting for about 16% of the country’s total wall materials. The Soviet Union has a total of 180 silicate brick factories, of which 40 percent are produced annually with an output of 60 million standard bricks, 30 percent are produced annually with an annual output of 60 to 90 million, and the rest are 90 million bricks per year. There are eight factories producing more than 200 million bricks per year. For every 1,000 standard bricks, the average consumption of lime with an activity of 65-66% is 452 kg; the amount of sand is 2.32 meters-3; thermal energy consumption
