摘　　要：研究了矿渣的种类、细度以及碱组分种类、碱溶液浓度等对碱矿渣水泥化学收缩的影响。结果表明,当碱组分为NaOH时,碱矿渣水泥28d龄期的化学收缩约为6～10ml/100g,与硅酸盐水泥(7～9ml/100g)的相当;当碱组分为水玻璃时,其收缩量约为3～6ml/100g,比硅酸盐水泥的小。The influence of different kinds and various specific surface area of granulated blast-furnace slag, of different type and concentration of alkali activators on the chemical shrinkage of alkali activated slag cement were studied. The results showed that the chemical shrinkage value of alkali activated slag cement activated by NaOH was about 6-10ml/100g which equivalent to that of ordinary Portland cement （about 7-10 ml/100g）, and it was about 3-6 ml/100g which was lower than that of ordinary Portland cement if it was activated by water glass.
