摘　　要：对碱激粉煤灰胶凝材料与水泥砂浆及混凝土的耐酸性及在干湿条件下的体积变化进行了试验研究,其中水泥为对比样。结果表明:与水泥相比,碱激发粉煤灰胶凝材料具有良好的抗硫酸侵蚀性、湿胀小、干缩大。结论是碱激发粉煤灰胶凝材料适合在潮湿环境或酸性水中使用,不宜在空气中使用。Properties of the mortar and concrete of alkali-activated fly-ash cementing material and ordinary Portland cement were studied through experiments,in which the cement was as control sample.The results showed that alkali-activated fly-ash cementing material has good sul- phuric acid resistance and low bulking factor and high drying shrinkage against ordinary Portland cement.It was a conclusion that the service envi- ronment of alkali-activated fly-ash cementing material will be appropriate for the moisture or acid water while not for the dry.
