摘　　要：该研究将废弃铜渣作为掺合料用于水泥生产,可大规模资源化利用废弃铜渣。铜渣以5%、10%、15%、20%的比例取代水泥制备铜渣-水泥复合胶凝材料。研究表明,随着废铜渣掺量增加,胶凝材料的标准稠度用水量增加,凝结时间延长。强度随着废铜渣掺量增加先增加后降低,最佳掺量为10%, 3 d抗折、抗压强度分别为4.7 MPa和27.4 MPa, 28 d抗折、抗压强度分别为8.6MPa和48.7 MPa。In this study,copper slag was used as admixture in cement production,which can be used as resources on a large scale.Copper slag replaced cement with 5%,10%,15%and 20%copper slag to prepare the composite cementitious material.The results showed that with the increase of copper slag content,the water consumption of standard consistency of the cementing material increased and the setting time prolongated.The strength increased first and then decreased,and the optimal content was 10%.The 3 d bending and compressive strengths were 4.7 MPa and 27.4 MPa,respectively.Meanwhile,the 28 d bending and compressive strengths were 8.6 MPa and 48.7 MPa,respectively.
