加速混凝土硬化,可以提高构件产量、加快模板周转和节省建厂投资。 迄今为止,国外已经研究并采用的加速混凝土硬化的方法,不下二十余种。但是蒸气养护,是目前各国广泛应用的一种方法。最近日趋广泛地应用化学外加剂,其优点 Accelerating the hardening of concrete can increase the production of components, speed up the turnover of the template, and save the investment in construction. So far, the method for accelerating the hardening of concrete that has been studied and adopted abroad has no less than twenty species. However, steam curing is a widely used method in various countries. Recently, chemical admixtures have become increasingly widespread and their advantages
