摘要
基于标准混凝土配合比,使用黄金尾矿替代细骨料制备混凝土,对混凝土的抗压强度、抗折强度进行检测.结果表明,黄金尾矿替代率对混凝土强度的影响呈非线性,在20%～30%之间存在最佳替代率.当尾矿替代率在10%～30%之间时,黄金尾矿混凝土的强度高于未掺黄金尾矿的混凝土,满足相关标准要求.
Abstract
Based on the standard concrete mix ratio,gold tailings are used to replace fine aggregates in the preparation of concrete,and the compressive strength and flexural strength of concrete are tested.The results show that the effect of gold tailings replacement rate on concrete strength is non-linear,and there is an optimal replacement rate between 20%and 30%.When the replacement rate of gold tailings is between 10%and 30%,the strength of gold tailings concrete is higher than that of concrete without gold tailings,which meets the relevant standard requirements.
