Cement is an essential ingredient in concrete. The cement industry is a major source of greenhouse gas emissions worldwide. Using cement in concrete as efficiently as possible without compromising quality is the simplest way to address this. Numerous materials that can partially replace cement in concrete are the subject of extensive research. The selection of the concrete's constituent materials to minimize adverse environmental effects is the primary component in the creation of sustainable concrete. Due to its enhanced performance and advantages, the use of natural supplemental cementitious materials from new sources is becoming more and more important in contemporary construction methods. India is producing more and more agricultural waste every day. These agricultural wastes can naturally break down in open areas. One possible tactic to support sustainable development in both urban and rural contexts is to construct buildings using materials that are produced locally. The world is currently paying attention to alternative material sources that are less detrimental to the environment. The study's goal is to determine the effects of using "banana leaves ash" and "corn cob ash" as cement substitutes by evaluating their pozzolanic properties when mixed with concrete. These materials are widely used because they offer several benefits, such as lifespan, energy efficiency, low maintenance costs, cost-effectiveness, fire resistance, excellent thermal properties, and versatility. Corn cob ash, a byproduct of the maize industry, has shown promise as a sustainable and versatile building material, according to research that is currently being published. This research employed banana leaf ash and corn cob ash as partial cement substitutes. The specific mix design is M25. Samples were made by replacing cement with 5%, 10%, 12.5%, and 15% corn cob ash. If the ideal percentage of corn cob ash replacement is maintained, additional cement can be substituted with 2.5%, 5%, 7.5%, and 10% banana leaf ash. The compressive, tensile, and flexural strengths of banana leaf ash and corn cob ash were tested after 7, 14, and 28 days of curing. The results were compared to those of ordinary concrete.
