Abstract

Abstract

Based on taking corrosion test of concrete immersed in 3.5% weight of NaCl,5% weight of Na2SO4 and compound solutions(3.5% NaCl+5%Na2SO4),it has been studied that the free chloride di ffusion and mechanical damage,based on relative Youngs modulus,of concrete tha t include two grades of strength and three types of mineral admixture.The results suggest that the free chloride content of C30 should be 2 times that of C50,and fr ee chloride diffusion coefficients be 1.7～1.95 times.Moreover,the mineral adm ixtures may improve chloride and sulfate ion resistance capacity of conc rete,and the sulfate decreases chloride resistance capacity of concrete,as well as the chloride decreases the sulfates damage speed of concrete.
