Information Paper 7/89 Effectiveness of surface coatings in reduced carbonation of reinforced concrete
Publication Year
1989
Document Status
Current
Abstract
The alkalinity released by cement hydration generally protects embedded reinforcing steel from corrosion. Carbonation of concrete to the depth of cover neutralises the protection and can lead to the formation of corrosion products on the steel and to cracking, rust staining and spalling of the concrete. Coatings are being specified increasingly, either as a preventive measure or as part of repair work, to control the carbonation rate of concrete. BRE has developed an accelerated test to determine the relative carbon dioxide resistance of such coatings. Results of recent studies using this test show that a variety of coating types, properly applied, can fulfil carbon dioxide resistance requirements.
