| 摘 要： | 选用1：3乙二醇-甲醇溶剂以相当高的选择性从掺固硫渣的水泥水化浆体中萃取钙矾石并采用返滴定法测定其含量，研究表明：水化早期（一般指7d之前）水泥浆体中，钙矾石含量随龄期的增长而增加，而在水化后期，钙矾石含量随期的增长有所减少且趋于平缓。

| Abstract: | AFt was extracted from cement paste containing sulphur - fixed ash using glycol and methanol (mixing ratio =1:3) as solvent, and its content was measured by back titration method. The results show that AFt in the cement paste increases with the age at early stage(before 7 days), however decreased with age at late stage. |
