摘　　要：探讨了铬渣的胶凝活性,研究了不同掺量铬渣对水泥浆体性能的影响。同时,通过掺入沸石、粉煤灰及矿渣微粉等矿物外加剂,探讨了这3种矿物外加剂对铬渣-水泥体系物理性能的影响及其对Cr(Ⅵ)的控制作用。结果表明,铬渣具有良好的胶凝活性,矿渣微粉的加入对Cr(Ⅵ)的浸出有良好的控制作用。The cementitious activity of chromium residue and the effect of different dosage of chromium residue on the physical properties of Portland cement were studied in this paper. And the influences and the control of different kinds of mineral additions were experimented through adding the zeolite, fly ash and blast furnace slag powder into the chromium-cement system. The results of this study shows that the chromium residue has good cementitious activity, and Cr（Ⅵ） concentrations in the leachate is decreased very much by adding the slag powder in the chromium-cement system.
