Abstract：
General technical measures, such as optimization of mix proportion and addition of atiseptic and corrosion-inhibiting admixture, etc., were adopted to study the method for improving corrosion resistance of concrete. Study result showed that grade-I pulverized coal ash plus S95 pulverized slag double admixture technique could improve the corrosion resistance of concrete; after addition of NST atiseptic and corrosion-inhibiting admixture, air content of concrete stayed at 4% to 6%, frost resistance of concrete was improved, chloride ion permeation resistance of concrete increased by 25% and sulphate resistance by 20%.
