Study on the Effect of Copper Slag Admixtures to Properties and Structure of Concrete
Song Jun-wei

Abstract: This study reports on an investigate the effect of using copper slag as a replacement of cement on the properties of concrete. The effects of using copper slag wastes on hydration, gelling properties, mechanical properties, pozzolanic activity and durability aspects of concrete are studied. It has been found that copper slag have micro pozzolanic effect in the study. The concrete batches with copper slag addition presented greater mechanical and durability performance. The mechanism of copper slag powder in composite cementitious materials is filling effect, activity effect and acceleration effect. The filling effect of copper slag can make matrix denser and the accelerating effect can accelerate the early hydration. The results pointed out that there is a potential for the use of copper slag as a supplementary cementing material to concrete production.
