The aim of this research focuses on preparation of high performance and high strength concrete by employing industrial waste to preserve the naturally raw ingredients of concrete. Due to increases in demand of cement with large scale production, resulting in creating a environmental problem. In this regard, an attempt was made to investigate the combined effects of incorporating mechanical properties of concrete specimens produced by using addition kenaf fibres and partially replacing of cement with silica fume on concrete specimens. The aspect ratio of kenaf fibre used in this study is 100. The parameter investigated in this project is M-30 concrete and cement were partially replaced with silica fume by the percentages of 5%, 10%, 15% and 20% by total weight of cement also, kenaf fibres were added in ratio of 0.5%, 1.0% and 1.5%. Test was carried out on standard specimens casted by composite mixes. Slump test carried out in all mix before casting test specimens to ascertain workability of fresh concrete. It was obtained that tensile strength of kenaf fibre increased with the increase in percentage of SF replacement. In this regard, silica fume in concrete decreases the quantity of cement in the construction purpose and addition of kenaf fibre in concrete and leads to better performance of high strength concrete and reduction in environmental problem.
