Enhancing Concrete Properties Using Sugarcane Bagasse Ash and Crushed Groundnut Shells as Partial Replacements for Cement and Fine Aggregate

This study investigates the potential use of Sugarcane Bagasse Ash (SCBA) as a partial replacement for cement and Crushed Groundnut Shells (CGS) as a partial replacement for fine aggregates in M25 grade concrete. The research aims to mitigate environmental issues posed by agricultural waste while promoting sustainable construction practices. A comprehensive experimental program was conducted with variations in SCBA (2%, 5%, and 10%) and a fixed 5% replacement of sand with CGS. Concrete properties were evaluated through slump tests and compressive strength tests at curing intervals of 7, 14, and 28 days. Results show that up to 10% SCBA and 5% CGS can effectively be used without compromising structural performance. The use of agricultural by-products presents a viable solution for eco-friendly and cost-effective construction materials.
