Abstract: In the present study, the cement is partially replaced by bagasse ash and the fine aggregate is partially replaced by slag sand to produce a high strength concrete. The water cement ratio is one of the important factors to describe the strength of the concrete. Therefore, the factors considered in this study are water binder ratio, bagasse ash to cement ratio and slag aggregate to fine aggregate ratio with 4 levels each and their levels are 0.30, 0.33, 0.36, 0.39 and 10%, 15%, 20%, 25% and 20%, 30%,40%,50% respectively. The mix proportions were obtained from Taguchi method of optimization. The cubes and cylinders were casted for the obtained mix proportions and were tested at 7 and 28 days for compressive strength and split tensile strength. The test results indicates that the highest strength of concrete is obtained by replacing 10% of cement by bagasse ash, 20% of fine aggregate by slag sand with a water cement ratio of 0.3. The regression analysis was done for the obtained results.
