Partial Replacement of Cement with Bagasse Ash in Concrete

The construction industry is one of the largest contributors to environmental degradation, with cement production being a major source of CO2 emissions. In response to this environmental challenge, the partial replacement of cement with alternative materials, such as agricultural byproducts, has gained significant attention. This project explores the use of Bagasse Ash (BA), a byproduct of sugarcane processing, as a partial substitute for cement in concrete. Bagasse ash, rich in pozzolanic properties, has the potential to improve the mechanical and durability characteristics of concrete while reducing its environmental impact. The study investigates the effects of varying percentages of bagasse ash (ranging from 5% to 30%) as a partial replacement for cement on the workability, compressive strength, and durability of concrete. The research includes experimental tests on fresh and hardened concrete, assessing properties such as slump, setting time, compressive strength, and water absorption. Results indicate that bagasse ash can be used effectively in concrete mixes, with the optimal percentage of cement replacement being 15%, achieving best balance of workability, strength, and durability. Beyond the environmental benefits, this substitution also leads to a reduction in the overall cost of concrete production. The findings of this study contribute to the growing body of knowledge on sustainable construction materials and provide valuable insights into the practical application of bagasse ash as a cement replacement. The results suggest that bagasse ash not only serves as an environmentally friendly alternative to cement but also enhances the long-term performance of concrete, making it a promising material for sustainable construction practices. The project advocates for further research to refine the mix design and explore other applications of bagasse ash in the construction industry, ultimately supporting the development of greener and more cost-effective building materials.
