摘　　要：为研究石墨尾矿混凝土的电阻率与力学参数的相关性,对掺量为40%的石墨尾矿混凝土外加0.4%的碳纤维制作的石墨尾矿碳纤维混凝土进行研究,对不同龄期的混凝土电阻率、回弹值和抗压强度进行测量。通过实验所得数据拟合建立电阻率、回弹值和混凝土抗压强度的数学回归方程,为通过电阻率来推断石墨尾矿混凝土的抗压强度的发展趋势提供定量分析的依据。In order to study the correlation between resistivity and mechanical parameters of graphite tailings concrete,the resistivity,rebound value and compressive strength of concrete at different cuning ages were measured by adding 0.4%carbon fiber into 40%graphite tailings concrete.Mathematical regression equations of resistivity,rebound value and concrete strength are established by fitting the experimental data,which can provide quantitative analysis basis for deducing the development trend of compressive strength of graphite tailings concrete by resistivity.
