Abstract

Chemical erosion of reinforced concrete by SO₄²⁻ in saline soil is the main factor of steel corrosion and concrete damage. Therefore, we synthesized a novel corrosion inhibitor based on barium salts for improving the SO₄²⁻ resistance property of concrete. In this study, the effects of corrosion inhibitor on the workability, compressive strength and SO₄²⁻ corrosion resistance property of concrete have been investigated. The results showed that with increased of corrosion inhibitor the slump of concrete has increased firstly and then decreased, compressive strength also showed a trend of firstly increasing and then decreasing. More importantly, with the increase of corrosion inhibitor, the SO₄²⁻ corrosion resistance property of concrete have improved obviously.
