Experimental Study on Sisal Fibre Reinforced concrete With Partial Replacement of Cement by Ground Granulated Blast furnace Slag

The study focuses on the compressive strength, split tensile strength, flexural strength performance of the blended concrete containing sisal fibre and different percentage of slag as a partial replacement of OPC. The cement in concrete is replaced accordingly with the percentage of 10 %, 20 % and 30 % by weight of slag and 1 % of sisal fibre is added by weight of cement. Concrete cubes are tested at the age of 7, 14, and 28 days of curing. Finally, the strength performance of slag blended fibre reinforced concrete is compared with the performance of conventional concrete. From the experimental investigations, it has been observed that, the optimum replacement of Ground Granulated Blast Furnace Slag Powder to cement is 20 % for M30 grade.
