混凝土预制构件生产中为达到要求的脱模或放张强度所必需的养护时间在整个生产周期中所占的比例最大,因此如何加速混凝土硬化以提高模板、台座的周转率与整个预制厂的生产效率并保证构件质量,就成了各国普遍重视的问题。十几年来各国在加速混凝土预制构件硬化方面做了不少研究工作,不仅是广泛采用的热养护方法有了发展,其他各种加速硬化的新方法及各种综合加速硬化法也均有所发
In the production of prefabricated concrete components, the maintenance time necessary to achieve the required demolding or tensile strength is the largest in the entire production cycle. Therefore, how to accelerate the hardening of concrete to increase the turnover rate of formwork and pedestal and the production of the entire prefab plant Efficiency and ensuring the quality of components have become a problem that countries generally attach importance to. Over the past decade, various countries have done a lot of research in accelerating the hardening of concrete prefabricated parts. Not only is the widely adopted method of thermal curing developed, but also various new accelerated hardening methods and various integrated accelerated hardening methods have been developed.
