Chloride Diffusion Coefficient and Steel Corrosion Properties of Concrete containing Hydrotalcite-based Corrosion Inhibitor

하이드로탈사이트계 방청제를 혼입한 콘크리트의 염화물확산계수 및 철근부식특성

Concrete can be used semi-permanently unless the steel is corroded. However, the concrete exposed to the marine environment is exposed to sea breeze, so chloride ions penetrate into the concrete and the steel is corroded accordingly. In order to solve these problems, there is a method of increasing the covering depth of the concrete and an application of the epoxy paint to the steel. In this study, the hydrotalcite type corrosion inhibitor was mixed with the concrete and the compressive strength, chloride diffusion coefficient and the corrosion properties of the steel were examined.
