| 摘 要： | 孔溶液的化学成分对混凝土电测渗透性有重要影响。理论分析和试验表明,混凝土粉末浸液的电导率与孔溶液的电导率有很好的相关性,重量比为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。 |

| Abstract: | The chemical composition of a pore solution has major effect on concrete permeability evaluated by electrical method.Analysis of test results shows that the conductivity of concrete pore solution and filtered mortar powder solution correlate well.When the ratio of powder to water is 3∶1,the correlation coefficient between the conductivity of the pore solution and the filtered mortar solution is 0855 0.Consequently,it is feasible to modify concrete permeability by the conductivity of a filtered concrete powder solution. |
| Keywords: | concrete permeability pore solution filtered concrete powder solution electric conductivity |
