Abstract:

Copper slag is the waste material obtained from smelting and refining of copper. Copper slag is one of the materials that is considered as a waste which could have a promising future in construction Industry as partial or full substitute of aggregates. For this research work, M25 grade concrete was used and tests were conducted for various proportions of copper slag replacement with sand of 0 to 50% in Self compacting concrete. Strength properties such as Compressive Strength, Split Tensile Strength, Flexural Strength, to be evaluated experimentally. The obtained results were compared with those of control SCC. The results indicate that the compressive strength, flexural strength and split tensile strength are increased up to 40% replacement of Copper Slag as Fine Aggregate in SCC. Addition of up to 50% of copper slag as sand replacement yielded comparable strength with that of the control mix. Further additions of copper slag caused reduction in the strength due to an increase of the free water content in the mix. Mixes with 80% and 100% copper slag replacement gave the lowest compressive strength. This research study was conducted to investigate the performance of copper slag in self- compacting concrete as partial replacement of fine aggregate. Therefore, it is recommended that 40% of copper slag can used as replacement of sand in order to obtain HPC with good strength and durability properties.
