The Study on Chloride Corrosion of Concrete Containing Admixture Mineral

Article Preview

Abstract:

Chloride ions were harmful to the performance of the concrete.Admixture mineral had been replaced part of cement in high performance concrete to improve the durability and chloride resistance of the concrete.In this paper,the compressive strength of the concrete with admixture mineral and without admixture mineral had been measured cured after 28 days. The results had been shown that the compressive strength of the concrete without admixture mineral is lower than the one with admixture mineral after 28ds’and 56ds’ immersing in 5%NaCl solution. The quantities of electricity through the concretes with 30% admixture mineral were lower than the benchmark concretes. The current of C30 and C40 concretes with admixture mineral was lower than the benchmark concretes.The concrete with admixture mineral had been eroded lower than the one without admixture mineral.
