【摘要】 以固体废弃物金尾矿砂为集料，以普通硅酸盐水泥与粉煤灰为胶凝材料，掺加一定的外加剂，调整用水量，制备了金尾矿砂砂浆。通过调整外加剂掺量以及用水量，所制备的金尾矿砂砂浆进行了稠度、3 d、7 d以及28 d的抗折强度以及抗压强度测试，表明外加剂及用水量对砂浆流动性及力学性能都有影响，通过调整外加剂掺量及用水量可以制备出符合规范性能要求的金尾矿砂浆。更多还原

【Abstract】 Gold tailings mortar was prepared by using solid waste gold tailings as aggregate, ordinary portland cement and fly ash as cementitious materials,adding certain additives and adjusting water consumption. By adjusting the amount of admixture and water consumption, the consistency, 3 d, 7 d and 28 d flexural strength and compressive strength of the prepared gold tailings sand mortar are tested. It shows that the admixture and water consumption have an impact on the fluidity and mechanical properties of the mortar. By adjusting the amount of admixture and water consumption, the gold tailings mortar can be prepared to meet the performance requirements of the specification.更多还原
