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。
採取高溫養護、粉煤灰磨細和水泥石內部補足堿3種方法，對大摻量粉煤灰水泥石的抗碳化性能進行改善，利用碳痠鹽定量分析法對改善後水泥石的抗碳化性能進行測試，結果錶明：高溫養護和粉煤灰的磨細對大摻量粉煤灰水泥石的抗碳化性能有較好的改善效果；補足堿對大摻量粉煤灰水泥石抗碳化性能的改善作用不大。
채취고온양호、분매회마세화수니석내부보족감3충방법，대대참량분매회수니석적항탄화성능진행개선，이용탄산염정량분석법대개선후수니석적항탄화성능진행측시，결과표명：고온양호화분매회적마세대대참량분매회수니석적항탄화성능유교호적개선효과；보족감대대참량분매회수니석항탄화성능적개선작용불대。
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.
