Evaluation of Protective Coatings to Reduce Chloride Penetration of Bridge Surfaces
The objective of this project is to evaluate the effectiveness of six different protective coatings in protecting concrete from intrusion of chlorides and to evaluate the life-cycle cost and performance of the products compared to linseed oil. The bridge surface was divided into eight sections with linseed oil applied to two sections as controls. A silane in water, epoxy in solvent, epoxy in water, resin in mineral spirits, polyester resin, and high molecular weight methacrylate resin were used on the other sections. Cores will be removed within two months of construction and after two, three, and five years of service. The surface permeability and chloride content at two levels will be determined and these values will be used to evaluate the effectiveness of the sealant.
