Enhancement of Mechanical Properties of Concrete Using Industrial Waste

In response to the evolving global landscape, there is a growing inclination towards embracing sustainable and environmentally conscious construction practices to meet the demand for more eco-friendly and climate-resilient built environments.In recent time several SCM (Supplementary Cementitious Material) had been employed in concrete for its property enhancement as well as reducing negative impact of waste on environment.Taking a step in the similar direction the present study employs Rice husk ash (RHA) and Waste marble powder (WMP) for strength enhancement of concrete.Varying percentage of Rice Husk Ash (0%, 2.5%, 5%, 10%, 12.5%, 15%&20%) and Waste Marble Powder (0%,2.5%,5%,10%, 12.5%, 15% & 20%) were used as a replacement of cement in binder.Further a combined replacement of RHA and WMP was used to prepare data cases for replacement of cement in concrete.Five different cases were designed with keeping RHA percentage constant for single case while varying the WMP percentage for same.Case 0 with no replacement, Case 1 with 2.5% RHA along with varying percentage of WMP, Case 2 with 5% RHA along with varying percentage of WMP similarly Case 3 with 10% RHA along with varying percentage of WMP and Case 4 with 12.5% RHA along with varying percentage of WMP.The varied percentage of WMP were 5%, 10%, 15% and 20% for each case.This resulted in identification of combined effect of both materials on concrete strength
