剪压法检测混凝土抗压强度试验技术研究

Test technology research on compressive strength of concrete by shear-pressure method

剪压法作为一种新的微破损方法,具有检测精度高、对结构损伤小、操作简单便捷等优点,值得推广应用。本研究通过不同混凝土龄期展开剪压、抗压强度的试验,在建立上海地区剪压法测强曲线的基础上,按照国内剪压法检测规程的惯例,推导出上海地区的线性回归方程f=A+BN。

Shear-pressure method as a new method of micro damage,with high precision,small to structural damage,and the advantages of simple operation and convenient,is worthy of popularization and application.This study through different concrete ages of shear-pressure and compressive strength test,the establishment of the Shanghai area strength-measuring curve on the basis of the study,according to shear-pressure method testing procedures of practice,deduce the linear regression equation of the Shanghai area f=A＋BN.
