Abstract
Generally, when using copper slag mixed into the concrete, due to higher weight of copper slag, a reduction in the compressive strength and durability of the hardened concrete to increased bleeding is caused. In this study, hence copper slag, a kind of by-product was used as an alternative to the fine aggregate, it was carried out in combination with the use of fly ash in eliminating disadvantage and recycling aspects. As a result of this study, the mixing of fly ash is decreased in the 50% of bleeding, 5% of drying shrinkage, 30% of carbonation test and improvement of 10% of compressive strength than that of copper slag only at most.
