The Effect of Different Surface Coatings on the Chloride Penetration into Concrete

Deterioration of concrete structures in marine environments, especially in the Persian Gulf region, is a serious problem mainly due to the chloride ingress into concrete. Since chloride ingresses into concrete from the surface, quality improvement of this area will result in higher impermeability of concrete. This could be achieved by optimizing the mixture proportion or/and employing surface treatments. Different types of surface treatments have different performance against chloride penetration into concrete. It is very important to determine an efficient type of these coatings for this region to increase service life of concrete structures. This paper presents laboratory obtained data of chloride penetration into concrete specimens with six different types of surface treatments that were immersed in 165 gr/lit NaCI solution for 5 months. Chloride protection efficiency and the influence of these surface treatments on service life of concrete structures are also evaluated. Accordingly, the most efficient surface coating against chloride has been proposed.
