The manufacture of cement contributes to environmental issues including pollution and global warming since it releases a number of dangerous gases. Natural sand is also expensive and difficult to get, thus in order to solve these issues, research is focusing on exploiting industrial and agricultural waste. Sugarcane Bagasse Ash (SCBA) is a leftover industrial by-product from the sugar industry’s captive power plant while agricultural waste known as groundnut shell ash (GSA) is used to substitute fine aggregates. The purpose of this paper is to observe the possibility of utilizing sizeable quantity of SCBA and GSA here place of cement and fine aggregate in developing of concrete. In this paper, concrete was batch-produced by weight using M30 mixed ratio. Concrete cubes, concrete cylinders and concrete beams were casted by 5% substitute of cement with SCBA and fine aggregates by GSA in different percentages (5%, 10%, 15%, 20%, and 25%). Concrete was followed via curing in normal water for 7, 28, and 56 days. In order to evaluate the reaction mechanism and hydration behavior of the produced concrete and paste mixes, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), Ultrasonic Pulse Velocity test (UPV), and mechanical strength tests were employed. The results showed that 15% replacement demonstrated the highest strength in compression, split tensile strength, and flexural strength.
