Protection effects of polymeric finishes on the carbonation of concrete and corrosion of reinforcement were experimentally examined by using accelerated carbonation testing(30°C, 60%R.H., CO2; 5% for 8 months) and accelerated corrosion testing(50°C, 95%R.H. for 16 months) for test specimens of reinforced concrete with many kinds of polymeric finishes. In order to evaluate the effectiveness of polymeric finishes as repairing materials for partly-deteriorated reinforced concrete, and also to obtain basic data for improvement of the durability of reinforced concrete by polymeric finishes, experimental data were systematically analyzed by the least-square method using parabolic law(√t law) involving a constant term, which was theoreti-cally derived for the progress of deterioration of reinforced concrete based upon unsteady state dynamic analysis. It was found that polymeric finishes play the important roles in the retardation of carbonation of concrete and the suppresion of corrosion of reinforcement in neutralized concrete with no chloride ions included under ordinary atmospheric environmental conditions.
