An experimental investigation was conducted to study the effect of using copper slag as a fine aggregate on the properties of cement mortars and concrete.
Therefore, it is recommended that up to 40–50% (by weight of sand) of copper slag can be used as a replacement for fine aggregates in order to obtain a concrete with good strength and durability ...
Compared to fine aggregate, copper slag, which was used in the study, has a fineness modulus of 2.20, a higher S.G of 3.83, and a bulk density of 2120 kg/m 3, resulting in concrete with a higher density. Further, water absorption is found to be 0.5%. According to these findings, copper slag has a lower surface porosity than sand and may require ...
