孔溶液的化学成分和电性能对混凝土渗透性的电测结果有重要影响.理论分析和试验表明,水灰比和粉煤灰的掺量对孔溶液的电导率影响很大.混凝土粉末浸液的电导率与孔溶液的电导率有良好的相关性,浓度为3:1的粉末浸液与孔溶液电导率的线性相关系数为0.8550.利用混凝土粉末浸液的电导率对混凝土的电测渗透性结果进行修正是可行的.
The chemical composition and electrical properties of the pore solution have an important influence on the electrical measurement results of concrete permeability.The theoretical analysis and tests show that the water-cement ratio and the fly ash content have a great influence on the conductivity of the pore solution.Concrete powder immersion Conductivity and conductivity of the hole solution has a good correlation, the concentration of 3: 1 powder immersion and conductivity of the hole solution conductivity linear correlation coefficient of 0.8550. The use of concrete powder impregnation conductivity of the concrete electrical penetration testing Correction of sexual outcomes is feasible.
