Abstract

The use of copper slag as a partial replacement for fine aggregate as copper slag has a shape that resembles sand and natural gradation. Physical form that is shaped flat copper slag and pointy (sharp) and most contain iron oxides and silicates and have stable chemical properties. The chemical composition of copper slag composed of Fe2O3, SiO2, CaO, Al2O3. This study was conducted to determine the effect of variations in the fine aggregate grading 25% copper slag replacement on the concrete compressive strength, modulus of elasticity, and absorption by using a fine aggregate gradation variation 1,2,3, and 4 copper slag replacement 25%. The results obtained absorption value of 1.5%, 1.62% 1.86%, 2:09%, which value is smaller than the normal concrete 2:59%, the highest compressive strength magnitude occurred in successive gradation variation of 15.71% 1,2,3,4, 12.03%, 5:01% and 1.81% of normal concrete. value contained in the largest modulus of elasticity of concrete gradation variation 4 with 25% aggregate replacement material refined by Ec = 29285.75 kg/cm2
