实践证明:同强度等级、相同施工条件浇筑的混凝土,养护程度较好者表面色泽好、光洁坚硬,养护较差者表层起砂、脱皮、龟裂较多,这将会严重影响其强度和耐久性。因此,深入研究和探讨混凝土养护方法及其实际效果,对提高混凝土结构工程的强度和耐久性有着十分重要的意义——
Practice has proved that: with the strength level, the same conditions pouring concrete construction, better maintenance of the surface color is good, bright and clean, poor maintenance of surface sand, peeling, cracking more, which will seriously affect its strength and durability Sex. Therefore, in-depth study and discussion of concrete curing methods and their practical effects, to improve the strength and durability of concrete structures has a very important significance -
