摘要：根据地方废弃物的特点，把铜矿尾砂和再生骨料结合起来，代替砂石应用到普通混凝土中，通过调整外加剂掺量，保持水胶比不变，制作相应试件，测定其抗压强度、抗折强度及耐久性。结果表明，掺铜矿尾砂及再生骨料并未导致混凝土抗压强度及抗折强度明显降低，甚至有所提高。保持水胶比不变，调整铜矿尾砂和再生骨料用量，对混凝土耐久性影响不明显。 Abstract: According to the quantity characteristics of local waste, copper tailings and recycled aggregates are combined to replace sand and gravel in ordinary concrete. By adjusting the dosage of admixtures and keeping the water-binder ratio unchanged, the specimens are made to determine their compressive strength, flexural strength and durability. The results show that in terms of strength, the compressive strength and flexural strength of concrete are not significantly reduced or even improved by adding tailings and recycled aggregates. To keep the water-binder ratio unchanged and to adjust the amount of tailings and recycled aggregates, the durability of concrete is not significantly affected.
