Abstract

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 0855 0.Consequently,it is feasible to modify concrete permeability by the conductivity of a filtered concrete powder solution.
