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 cementi-tious 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.
