Abstract

Abstract

The effect of different wet curing period on carbonation resistance of grade 25 concretes including purified cement concrete A and three double-adding concretes(FA+SL) B,C and D was investigated under dry-cold climate via accelerated carbonation test.Liner equation between carbonation coefficient and different wetcuring period was proposed.The results show that in order to guarantee concrete service life of 50 years,A should be wet-cured for 11.2 d at least,and B,C and D should be wet-cured for 11.1 d,12.9 d and 14.5 d respectively.The more mineral admixture concrete contains,the longer the wet-curing period of concrete is for ensuring adequate carbonation resistance
- wet-curing period,
- carbonation resistance,
- dry-cold climate,
