在制造混凝土制品的工厂中,利用热能提高混凝土温度,加速混凝土硬化,以谋求在早期达到脱模强度,提高模板的周转率和生产率。如在早期达到所需的混凝土强度,就能提前出厂,并能有效地使用成品堆放场。从工序顺序看制品工厂中热能的利用,有加热材料或在搅拌时使用高温蒸汽的热混凝土,已在板状预制构件中采用;但是,通常用在成型后的养护工序中,加速混凝土硬
In factories that manufacture concrete products, thermal energy is used to increase the temperature of the concrete and accelerate the hardening of the concrete in order to achieve early release strength, increase the turnover rate and productivity of the formwork. If the required concrete strength is reached early, it can be delivered in advance and the finished product yard can be effectively used. The use of thermal energy in the product factory is seen from the process sequence. Hot concrete with heated material or high-temperature steam during agitation has been used in plate-shaped prefabricated components; however, it is usually used in the post-molding curing process to accelerate concrete hardening.
