【摘要】 开展矿物掺合料混凝土的电阻率测定和立方体抗压强度试验,以分析研究原材料如水胶比、单位立方米水泥用量、单位立方米胶凝材料用量对混凝土早期电阻率的影响,早龄期电阻率与后期立方体抗压强度间的相关关系。结果表明:7d电阻率与水胶比间呈显著的线性相关关系,随单位立方米水泥用量和单位立方米胶凝材料用量的增加而增加,并均呈显著的非线性回归关系。混凝土后期立方体抗压强度随7 d电阻率的增加而增加,并均呈现显著的非线性回归关系。更多还原

【Abstract】 Cube crushing strength test and resistivity measurement of mineral admixture concrete was carried out to analysis the regression relationship between early age resistivity and raw material and mechanical properties.Test results showed that 7 d resistivity had a good linear correlation relationship with water-binding material ratio,increased with the increase of cement amount per cubic meter and cementitious material amount per cubic meter.Later age cube crushing strength increased with the increase of 7 d resistivity,and all had a good nonlinear regression relationship with 7 d resistivity.更多还原
