Evaluation of Carbonation Resistance Properties of Fly Ash Concrete Exposed to Various Environments

Abstract

We extracted and analyzed the evaluation results of accelerated tests from existing studies to understand the actual situation. As a result, it was revealed that the amount to which fly ash contributes to carbonation resistance in accelerated carbonation test may have been evaluated as almost zero. Then, we extracted and analyzed test results in actual environments. We took a contribution degree to the carbonation resistance property into consideration. Based on the considerations, it was revealed that, the evaluated level of binding material contribution degree under accelerated tests condition showed approximately a 12.5% than that of under the actual environment conditions.
