摘要
选用Ⅱ级粉煤灰和ＳＮ－Ⅱ型高效减水剂，采用“超量取代法”配制了水胶比在０．３－０．４范围、粉煤灰最大取代水泥量５０％的粉煤灰混凝土，以Ｎａ２ＳＯ４溶液浸泡法研究了水化早期混凝土抵抗硫酸盐侵蚀的能力，着重讨论了低水胶比条件下，粉煤灰掺量、水胶比及水泥品种等因素对粉煤灰混凝土耐硫酸盐侵蚀性能的影响。
The paper generate fly ash concrete,which is0.3~0.4 ratio of water and glue and fly ash intead ofcement maxium quantity,50%,by Ⅱ stage fly ash andSN-Ⅱ high effectiveness water reducer.the same time,the paper research concrete corrosion resistivity againstsulphate,and discuss the influence of quantity of flyash,ratio of water and glue and cement variety for flyash conerete collision resistivity against sulphate withlower ratio.
