Concrete; service life; corrosion inhibitor; chlorine resistance.Abstract
Concrete structures generally play an important role in the infrastructure construction. The corrosion of reinforcing steels in concrete structures is one of the main causes of the degradation and reduction of their service life, especially when they are exposed to marine environment or de-icing salts. An understanding of the process of chloride transportation in concrete is of great importance for engineers to predict the service life of concrete structures. Therefore, we synthesized corrosion inhibitor for improving the chlorine resistance of concrete.
