摘要
Abstract
In this paper,the carbonization resistance of fly ash concrete and the evolution law of fly ash content under different cycle conditions(dry and wet,freeze-thaw,dry-wet and freeze-thaw)were studied.The results show that the carbonization depth of fly ash concrete is first negatively correlated with the content of fly ash and then positively correlated with the short carbonization time under single dry-wet and freeze-thaw cycles.When the carbonization time is long,the carbonization depth of fly ash concrete is positively correlated with the content of fly ash.Under the coupled dry-wet-freeze-thaw cycle,no matter what kind of carbonization time(7、21、28 d),the carbonization depth of fly ash concrete is positively correlated with the content of fly ash.关键词
