摘　　要：以天津市常用混凝土C30、C35、C40、C50和C60的实体模型及相对应的试块为研究对象,分别采用立方体试块抗压法、回弹法和钻芯法测定混凝土的抗压强度。研究发现在冬期施工时,即使混凝土的强度等级不同,但各自置于标准养护和同条件养护条件下的试块的强度曲线的形状大体相同,在误差允许的范围之内,强度曲线大体呈对数曲线趋势。This paper took the commonly used C30,C35,C40,C50 and C60 entity model and the corresponding block as the research object in Tianjin,adopted the test cube compressive method,rebound method and core method respectively for determining the compressive strength of concrete. The study found that in winter construction,even if the strength grade of concrete was different,but the shape of block strength curve was approximately the same under the condition of same condition maintenance and standard curing,within the range of allowable error,trend strength curve was generally a logarithmic curve.
