近几年来,苏联的许多钢筋混凝土制品工厂开始采用热成型工艺。所谓热成型工艺,是将混凝土混合物在搅拌的同时,用蒸汽或电流加热到80～95℃,然后浇灌成型。采用这种工艺,可以加速混凝土的早期硬化,从而大大缩短拆模周期和提高模板的周转率。30年代,就有人认为用蒸汽加热混凝土混合物,在原则上是可行的。当时已经清 In recent years, many of the Soviet Union’s reinforced concrete products factories have begun to use thermoforming processes. The so-called thermoforming process is to heat the concrete mixture to 80-95°C with steam or electric current while stirring, and then water-molded. With this process, the early hardening of the concrete can be accelerated, thereby greatly shortening the cycle of demolding and increasing the turnover rate of the template. In the 1930s, it was thought that steam heating of concrete mixtures was, in principle, feasible. It was already clear
