Research on antiseptic and corrosion-inhibiting admixture for concrete

Concrete buildings in coastal area are dual attacked by chloride and sulfate easily. The erosions make great damage to buildings. This research develops a new type of antiseptic and corrosion-inhibiting admixture for concrete. It is a kind of inner-adding inorganic powder and made up by compaction component, corrosion-inhibiting component and sodium nitrite. The test results show that this admixture has the ability to resistant chloride and sulfate erosion, the admixture also can prolong service life of buildings which are exposed to high concentration of chloride and sulfate.
