A Model for Predicting the Carbonation Depth of SCC with Massive Fly Ash in the Loading State

Abstract:

In this work, four series of SCC specimens which cement replacement ratio by fly ash was 30, 40, 50, and 60% , respectively, and one series of normal concrete comparative specimens were designed. For the same series specimens, the fly ash addition was fixed, but the loading value was 0.0, 0.2, 0.4, and 0.6 times of the 28 d concrete flexural strength, respectively. Using accelerated carbonation test, the effects of fly ash additions, tensile stress rates, and compressive stress rates on carbonation rate of SCC are studied. Based on the test results, a model considered both effects of fly ash addition and stress rate for predicting the carbonation depth of SCC under real environment conditions is set up. These results can provide a reference for carbonation resistance design of SCC.
