摘要
研究了新疆市场上三种聚羧酸系外加剂与乌鲁木齐地区的三大品牌的普通硅酸盐42.5水泥的相容性。得出结论:三种水泥与聚羧酸系外加剂的相容性情况为屯河水泥较好,天山水泥其次,青松水泥较差。相容性较好的水泥与每一种聚羧酸系外加剂相容性均相对较好,相容性较差的水泥则与每一种外加剂的相容性均相对较差。粉煤灰矿物掺和料对聚羧酸系外加剂与水泥的相容性有较好的调节作用。
Study was carried out of compatibility of three series of polycarboxylate admixtures on Xinjiang market with three major brands of 42.5 ordinary portland cements currently used in Urumqi region. Compatibility of three kinds of cements with polycarboxylate admixtures was concluded as follows： best for Tunhe cement, next for Tianshan cement and poor for Qingsong cement. The cement of better compatibility was relatively better compatible with each kind of polycarboxylate admixture whereas the cement of poor compatibility was relatively worse compatible with each kind of polycarboxylate admixture. Mineral admixture of fly ash exerted a better modulating effect on compatibility of polycarboxylate admixture with cement..
