摘　　要：由于养护条件、成型方法以及试块体积的差异,混凝土标准养护试块强度不能完全代表结构实体的混凝土强度,而混凝土同条件养护试块强度和结构实体强度有很好的相关性,能够较好地反映结构实体的混凝土强度。根据试验期间气温的记录,采用成熟度(℃.d)代替养护龄期,建立了结构实体的混凝土强度和同条件养护试块强度的换算关系,计算结果与试验结果较好符合。The correlation of three kinds of strength was analyzed, and the relationship of concrete strength with curing time was also discussed. It can be found that the compressive strength of cubic specimens cured under the same condition as the structures was a better characteristic strength represented the real strength of structural concrete. By recording the temperatures of everday during the curing age, the strength of cubic specimens cured under the same condition as the structures and the strength of structural concrete by drilling method in different curing time, the simple maturity method was introduced. With this method, the strength of structural concrete at the random curing time can be ascertained.
