Carbonation of Surface Protected Concrete with Silicone Material
Concrete structures are exposed to carbonation that may cause rapid decay, shortening their service life and raising maintenance and repair costs. Carbonation lowers the alkalinity of the concrete depassivating the steel reinforcement. The prescriptive methodology is not a guarantee to obtain the desired service lives of 50 or 100 years. Surface treatment is commonly used to improve the resistance of concrete to carbonation. Using the silicone materials to an immersion treatment can effectively block the invasion of harmful substances,the carbonation of concretes with surface protection with silicone materials was evaluated. The results showed silicone can lower carbonation depth than the non-protected concretes. The carbonation depth will not increase significantly in the latter part of the concrete service.
