description abstractA simplified mathematical model for concrete carbonation has been developed and compared with data from accelerated and real exposures. A chamber for an accelerated carbonation test has been built, and the results derived from the test have been used to propose the simplified mathematical model. Two different concrete specimens, denoted S1 and S2, were exposed. For S1 concrete, the proposed mathematical model is a mass balance among CO2, Ca(OH)2, and C-S-H and takes into account the change of the porosity with time. Two different simulation software programs were employed to solve the set of differential equations. The model fits well experimental results reported in other works allowing prediction of service life in concrete structures. On the other hand, S2 concrete did not suffer carbonation. A comparative analysis of behavior of both specimens was made.
