选取了6种常用的工程纤维，开展纤维混凝土电阻率测试与抗压强度试验，研究分析纤维品种及龄期对混凝土抗压强度和电阻率的影响，建立纤维混凝土抗压强度和电阻率的定量关系。研究结果表明：掺入不同品种的纤维后，混凝土的抗压强度和电阻率均有不同程度提高，纤维自身的弹性模量和抗拉强度对混凝土抗压强度影响显著。混凝土抗压强度随电阻率的增高而增大，二者具有良好的非线性关系。根据混凝土电阻率测试结果，可对混凝土的强度发展趋势进行预测，也可基于混凝土抗压强度测试结果，间接评价混凝土的混凝土损伤程度和钢筋锈蚀速率。

The resistivity test and compressive strength test of fiber reinforced concrete were conducted,and the effects of fiber varieties and age on the concrete compressive strength and resistivity were studied. Then,the quantitative correlation between compressive strength and electrical resistivity of the fiber concrete was established. The results show that the compressive strength and resistivity of different varieties fiber concrete are improved in different degree,and the effect of elastic modulus and tensile strength of the fiber itself on compressive strength of concrete is significantly. The compressive strength of concrete increases with the increase of resistivity,which the two have good nonlinear correlation. According to the test results of concrete resistivity,the compressive strength development of concrete can be predicted,also the damage degree of concrete or steel corrosion rate can be evaluated base on the test results of concrete strength.
