摘要：研究了黄金尾矿粉掺量（0、10%、20%、30%）对净浆流动度和强度的影响，并对净浆配合比进行了优化；在此基础上，研究了黄金尾矿粉掺量对混凝土坍落度和强度的影响。结果表明：黄金尾矿粉的掺入增大了净浆的流动度，但降低了强度，可通过适当降低水胶比的方式优化净浆配合比；优化后掺黄金尾矿粉净浆的流动度与对照组相当，且随着黄金尾矿粉掺量从10%增至30%，净浆试件的抗压强度逐渐增大；在混凝土坍落度基本相同的前提下，当黄金尾矿粉掺量为30%时，混凝土试件的28 d抗压强度较对照组仅降低了5.88%；当黄金尾矿粉掺量为10%时，混凝土试件的28 d劈裂抗拉强度相对最高。 Abstract: The effects of the content of gold tailings powder(0, 10%, 20%, 30%) on the fluidity and strength of cement paste were investigated, and the mix proportion of cement paste was optimized. On this basis, the effect of the content of gold tailings powder on the slump and strength of concrete was studied. The results show that, the incorporation of gold tailings powder increases the fluidity of cement paste, but reduces the strength, and the mix proportion of cement paste can be optimized by appropriately reducing the water-binder ratio. The fluidity of the cement paste with gold tailings powder is comparable to that of the control group after optimization, and with the increase of the content of gold tailings powder from 10% to 30%, the compressive strength of the cement paste specimen increases gradually. Under the premise that the slump of concrete is basically the same, when the content of gold tailings powder is 30%, the 28 d compressive strength of concrete specimens is only 5.88% lower than that of the control group. And when the content of gold tailings powder is 10%, the 28 d spliting tensile strength of concrete specimens is relatively highest.

Abstract: The effects of the content of gold tailings powder(0, 10%, 20%, 30%) on the fluidity and strength of cement paste were investigated, and the mix proportion of cement paste was optimized. On this basis, the effect of the content of gold tailings powder on the slump and strength of concrete was studied. The results show that, the incorporation of gold tailings powder increases the fluidity of cement paste, but reduces the strength, and the mix proportion of cement paste can be optimized by appropriately reducing the water-binder ratio. The fluidity of the cement paste with gold tailings powder is comparable to that of the control group after optimization, and with the increase of the content of gold tailings powder from 10% to 30%, the compressive strength of the cement paste specimen increases gradually. Under the premise that the slump of concrete is basically the same, when the content of gold tailings powder is 30%, the 28 d compressive strength of concrete specimens is only 5.88% lower than that of the control group. And when the content of gold tailings powder is 10%, the 28 d spliting tensile strength of concrete specimens is relatively highest.
