【摘要】 以纯化学试剂配料，研究了 ＳＯ_３对阿利特－硫铝酸盐水泥熟料中Ｃ_３Ｓ，Ｃ_４Ａ_３矿物形成的影响。结果表明，一定量的ＳＯ_３能改善生料的易烧性，促进系统中ｆ－ＣａＯ的吸收，并能保证 Ｃ_４Ａ_３矿物良好形成及有利于Ｃ_３Ｓ的形成。而当ＳＯ_３含量较高时，将阻碍Ｃ_３Ｓ的形成并导致熟料中ｆ－ＣａＯ升高。更多还原

【Abstract】 The influences of SO₃ on the mineral formation of alite-sulphoaluminate cement are studied in the is paper. The, results show that, a suitable amount of SO₃ can improve the burnability of raw mix, benefit f - CaO combination, promote the formation of mineral C₄A₃. But higher content of SO₃ will hinder the formation of C₃S and the content of free lime be comes high.更多还原
