直拔法检测混凝土强度影响因素研究

Research on the Factors Affecting the Compressive Strength Test of Concrete by Direct Pull-out Method

直拔法是一种全新的混凝土强度检测技术,为了解各种影响因素对直拔法检测混凝土抗压强度的影响程度,本文通过对不同高径比等5种影响因素的比对试验,分析了这几个因素的影响程度。研究结果表明,除了芯柱直径的影响较大以外,其他的影响因素对检测混凝土抗压强度的影响均较小,可以忽略。另外,本文还对各种影响因素提出了相应处理方法。

Direct pull-out is a new method in testing compressive strength of concrete. To understand the factors affecting the testing result accuracy, the five different variables, including aspect ratio, are studied, and the affecting degrees of these factors are analyzed. The results show that the diameter size is the dominant factor in affecting result accuracy except core sample diameter. The methods to solve the problems of the factors are suggested, which should be considered in testing compressive strength of concrete.
