Study on Chloride Ion Penetration of Early Age Concrete Mixed Corrosion Inhibitor

Chloride ions begin to erode concrete in early age. In this paper, the rule of diffusion coefficient and the development of effective porosity of early age concrete mixed corrosion inhibitor in different concentrations of salt solution are analyzed through coulomb electricity method and the effective porosity test. Results show that the chloride ion penetration resistance of early age concrete increase with increase of age, weaken with the increase of chloride ion concentration. Effective porosity decreases with the increase of age and the concentration of sodium chloride solution. Concrete mixed corrosion inhibitors can effectively reduce the coefficient of permeability, the early effect is better than the late.
