摘　　要：采取高温养护、粉煤灰磨细和水泥石内部补足碱3种方法,对大掺量粉煤灰水泥石的抗碳化性能进行改善,利用碳酸盐定量分析法对改善后水泥石的抗碳化性能进行测试,结果表明:高温养护和粉煤灰的磨细对大掺量粉煤灰水泥石的抗碳化性能有较好的改善效果;补足碱对大掺量粉煤灰水泥石抗碳化性能的改善作用不大。Three methods,including high temperature curing,the grinding of fly ash and addition of alkali in cement paste,are adopted to improve anti-carbonation property of high-addition fly ash hardened cement paste.Then,the carbonate quantitative analysis is used to test the anti-car-bonation property of high-addition fly ash hardened cement paste.The results show that the high temperature curing and the grinding of fly ash can well improve anti-carbonation property of high-addition fly ash hardened cement paste,however,the addition of alkali in cement paste has a very poor effect.
