Experimental Study on Carbonation Resistance of High Volume Fly Ash Concrete under Different Curing Conditions
摘要
Abstract
Effect of different curing conditions and fly ash contents on the carbonation characteristics of high volume fly ash concrete were investigated via accelerated carbonation method, the microstructure and pore structure of high volume fly ash concrete were analyzed by SEM and MIP.The results show that the carbonation resistance of fly ash concrete after standard curing is larger than that of the fly ash concrete after natural curing;With the increase of fly ash content, the anti-carbonization ability of concrete decreases;The porosity of fly ash concrete under standard curing is reduced by 19.6% compared with that under natural curing;The pore size is refined and the porosity decreased by 31.4% after the carbonization.关键词
