Comparison between accelerated and natural carbonation results in different concretes
Carbonation is one of the main contributors to reinforcement corrosion. The testing of concrete carbonation is usually done by introducing the specimens in chambers of different C02 concentrations. The present paper describes an evaluation of the effectiveness of accelerated carbonation testing as a mean of prediction of the natural process of carbonation of concrete. The concrete samples were submitted to natural (0.03.% C02) and accelerated (5 % or 100 % CO2) carbonation. The results are compared by calculating the diffusion coefficients and the depth of carbonation. They show that accelerated carbonation of concrete changes with respect to that found in natural conditions when supplementary cementing materials are present.
