苏联每年生产大约两亿立方米混凝土拌合物。为生产如此数量的混凝土,广泛采用了自动化的固定式混凝土搅拌站和商品混凝土中心工厂。其特点是布局紧凑,工艺设备分布合理。这些搅拌站和工厂通常都是混凝土构件厂的一个组成部分,或者设置在现浇工程量大而集中的建筑群附近。实践表明,仅仅依靠固定式搅拌站和工厂,不能充分满足建筑工程对商品混凝土需要量的增长。这是因为商品混凝土的供应距 The Soviet Union produces about 200 million cubic meters of concrete mix annually. In order to produce such quantities of concrete, automated stationary concrete mixing plants and commercial concrete center plants are widely used. Its characteristics are compact layout, reasonable distribution of process equipment. These mixing plants and factories are usually an integral part of the concrete component factory, or they are located in the vicinity of a large and concentrated building group. Practice has shown that relying solely on stationary mixing plants and factories cannot fully meet the increase in demand for commercial concrete for construction projects. This is because of the supply of commercial concrete
