Abstract:The experiment used four kinds of P·Ⅱ42.5R cement that with different clinker mineral composition to prepared three concrete systems, which used fly ash of class Ⅱ and limestone powder as gelled material: an unmixed system A, a mixed fly ash system B and a mixed limestone powder system C. The curing conditions of A are (20±2) ℃ and RH above 95% and the curing conditions of B and C are (15±1) ℃ and RH (60%±5%). After the curing (28 d), the accelerated carbonation test was carried out. The results showed that under the standard curing conditions of (20±2) ℃ and RH above 95%, the concrete prepared by the cement with a high C2S content has a better anti-carbonation performance. Under non-standard curing conditions of (15±1) ℃ and RH (60%±5%), the concrete prepared by the cement with a high C3S content has a better anti-carbonation performance. A well curing condition is important to improve the anti-carbonation performance of concrete
