PERFORMANCE CHARACTERISTICS OF AN ACRYLIC RUBBER PROTECTIVE COATING SYSTEM FOR CONCRETE DURABILITY IN A MARINE ENVIRONMENT

This paper presents test data on the ability of a highly elastic acrylic rubber coating to resist the penetration of both chloride ions and carbon dioxide. In addition, the bond strength of the coating to the concrete substrate when subjected to repeated cyclic wetting by chloride solution and drying is also reported. The chloride ion penetration resistance of the coating and its bond strength to concrete were studied by exposing reinforced concrete slabs, some fully coated and others half-coated, and made with three water-cement ratios, to cycles of wetting with 4 percent sodium chloride solution and drying. The tests were carried out for 50 cycles extending over a period of over 500 days. Results show that this acrylic rubber coating has excellent resistance to both chloride ion penetration and carbonation.
