Abstract

The reuse of mineral wastes is one of the most suitable solid wastes solutions. Throughout the world, the large of the granular aggregates used in constructions exploit natural mountain resources and rivers. Using mineral waste as a part of concrete, it can be helped to create a green environment and also contribute to sustainable development. Since the copper production process in the Sarcheshmeh copper condensation factory is the source of the production of slag as waste and useless materials. These wastes can be used to produce concrete. In this paper, that is based on a laboratory study, attempted to examine the physical and chemical properties of waste materials. The effect of these materials as sand replacement was studied on the properties of Self-condensation, strength, corrosion and absorption of water self-compacting concrete. Thus, sand was replaced with the percentages of 0, 20, 40, 80 and 100 with copper slag, and the effect of this replacement on properties of self-condensation, strength, corrosion, and water absorption of self-compacting concrete studied. The results indicate that the replacement of sand with copper slag has caused an increase in slump flow and by increasing the percentage of replacement an increase in the rate of obstruction was observed. The compressive strength with the replacement of sand, with 20, 40 and 60 percent of copper slag, increased by 11.3, 15.5 and 12.4% respectively. And replacing sand with copper slag will cause more concrete corrosion.
