PROTECTION OF CONCRETE AGAINST CARBONATION

Concrete can be protected against carbonation either by protective coatings such as high quality emulsion paints or polymer modified cementitious slurries. The permeability to carbon dioxide, as measured in the laboratory, correlates very well with the field test. The carbonation rate of concrete can also be reduced by the incorporation of suitable film forming thermoplastic polymers in the mortar, provided that the porosity of the mortar is not too high. The results indicate further that the curve of carbonation shows little progression with increasing exposure time. The rate of carbonation in sheltered concrete is higher than on exposed, frequently rain soaked concrete. (A) For the covering abstract see IRRD 867793.
