Impact of Using RHA and CD in Replacement of Cement for Mix

The introduction of sustainable development to overcome issues of natural resource depletion has been gaining increased attention. The major objective of this study is to address the potential use of both agricultural and industrial wastes namely RHA (Rice Husk Ash) and CD (Copper Dust) as raw material in production of concrete. This study is an experimental investigation performed on replacement of copper dust and rice husk in cement concrete. It enhances the mechanical properties of concrete cube subjected to split tensile test and compressive strength test .This study provides comparison between the performance of using copper dust and rice husk cement concrete, as a strengthening material of concrete cube. The samples were tested and proved its promising results which were found to be increased compressive strength upto 25% and increased split tensile strength upto 40%.
