摘要
为了改善铜尾矿粉-水泥胶凝材料的力学性能,将纳米ZnO按照0%~1.0%的质量比加入铜尾矿粉-水泥中,测试抗压强度、抗拉强度和抗折强度。结果表明,当ZnO掺入量为0.5wt%~1.0wt%时,铜尾矿粉-水泥胶凝材料的力学强度得到了明显的改善。
In order to improve the mechanical properties of copper-tailing powder-cement cementitive material,nano-ZnO was added into copper-tailing powder-cement at a mass ratio of 0%~1.0%to test the compressive strength,tensile strength and flexural strength.The results show that when the amount of ZnO is 0.5 wt%~1.0 wt%,the mechanical strength of copper-tailing powder-cement cementitious material is improved obviously.
