结构混凝土强度指标试验的研究

The Strength acceptance Limit of the Structural Concrete

本试验通过测定两个厂家的混凝土标准养护试块强度、同条件养护试块强度以及结构实体取芯强度,分析三者之间的相互关系及造成其差异的因素,得出三种强度的相关关系式,找出检测结构实体混凝土强度与混凝土强度等级判定标准之间的切合点。

The strength of concrete under the standaud curing and, the same curing condition ot the structures of twoconcrete companies is determined in this experiment. As the most direct putative strength, the strength of the specimens taken out from the structure is also analyzed. Through discussing the correlation and the influencing factous between the strength listed before, the correlative foumulas aue given out. The appropriate methods to test the structural concrete strength and to determine the grade of the structural strength are also introduced in this thesis.
