莫斯科民用建筑总局东列阔夫斯基钢筋混凝土构件厂,在兹洛夫斯基振动压实成型机上生产普通与轻质混凝土制品。为提高成型效率和减少水泥用量,采取了在连续式搅拌机中直接蒸汽预热混凝土拌合物的工艺方法。从1971年以来,该厂以这种工艺共生产了48000立方米混凝土制品。混凝土拌合物的蒸汽预热是在C-780型连续式强制搅拌机中进行的(图1)。热蒸汽通过喷嘴进入搅拌机内,几个喷嘴从两侧 The Moscow State Civil Construction Bureau’s East Lekovsky Reinforced Concrete Component Plant produces ordinary and lightweight concrete products on a Zlowski vibratory compaction machine. In order to increase the molding efficiency and reduce the amount of cement, a process method of directly steam preheating the concrete mixture in a continuous mixer was adopted. Since 1971, the plant has produced a total of 48,000 cubic meters of concrete products in this process. The steam preheating of the concrete mix is ​​carried out in a continuous forced mixer C-780 (Figure 1). Hot steam enters the mixer through nozzles, several nozzles from both sides
