在硅酸盐水泥熟料中加入铁矾渣，制备成胶凝材料。分别以粉煤灰沸石、硫化钠和粉煤灰为外加剂，研究其对水泥固化体强度和浸出毒性的影响。在胶凝材料中铁矾渣加入量为60％时，加入沸石、硫化钠为稳定剂，均可提高重金属离子的稳定性，不同固化体的浸出毒性值均低于国家标准。在胶凝材料中加入粉煤灰，粉煤灰掺量增加，固化体强度下降，不同固化体的浸出毒性值也均低于国家标准。

Cementitious materials were prepared by adding jarosite slag in portland cement clinker.The effect of additives(fly ash zeolite,sodium sulfide and fly ash)on the solidified body strength and leaching toxicity were studied,respectively. When the jarosite slag content was 60% in cementitious material,the stability of heavy metal ion in solidified body were improved by adding zeolite,sodium sulfide as stabilizer and leaching toxicity values of different solidified body were lower than the national standard. When the fly ash was added in cementitious material,fly ash content increased,the strength of solidified body decreased,the leaching toxicity values of different solidified body were also lower than the national standard.
