摘　　要：研究了河北辛集、广西柳州的硫酸渣对水泥性能的影响。结果表明,硫酸渣对水泥性能的影响与一般火山灰质材料基本一致,不同的是硫酸渣具有改善水泥的体积安定性、提高耐硫酸盐侵蚀和后期强度增进率小的特点。The effect of the addition of sintered pyrites slag sampled from Xinji and Liuzhou on cement properties was studied. The result showed that the effect of sulfate slag was similar to that of pozzolanic materials on cement properties, while the difference was that sintered pyrites slag could improve the volume soundness and sulphate resistance of cement, and the cement long-term strength growth rate could also be improved.

关 键 词：硫酸渣 体积安定性 耐硫酸盐侵蚀
