摘　　要：将制革过程中产生的铬革屑进行两种等级的粉碎(0.02、0.05 mm)后作为增韧纤维添加到固井水泥浆中,考察铬革屑用量与固井水泥浆的浆体力学性能关系。扫描电镜观察水泥石断面显示,铬革屑与水泥基体粘结良好,铬革屑的交联作用导致了明显的增韧效果。研究结果表明,铬革屑添加到固井水泥具有可行性,有进一步深入研究的价值。为铬革屑的资源化利用提供了一种新的途径。After two levels of grinding （0.02, 0.05 mm） for the chrome shavings produced during tanning process, and added it as toughening fiber to the cement slurry, then the relationship between the amount of chrome shavings and mechanical properties of cement slurry was investigated. The SEM pictures indicated that the chrome shavings had a good bonding effect on cement matrix. Due to the cross-linking of chrome shavings, the cement has the better property of toughening effect. Therefore, this technology is feasible and valuable. It provides a new way to recycle the chrome shavings.
