Experimental study of cement with ground nut shell ash & cashew nut shell ash with discarded nano nylon powder concrete for sustainable environment

ABSTRACT This study explores the use of Ground Nut Shell Ash (GNSA), Cashew Nut Shell Ash (CNSA), and Discarded Nylon Fiber (DNF) as supplementary materials in cement concrete to enhance sustainability. Mechanical properties such as compressive, tensile, and flexural strengths were analyzed for concrete mixtures with varying proportions of these materials. Results indicate that the optimal blend increased compressive strength by 15%, tensile strength by 10%, and flexural strength by 12% compared to conventional concrete. Improvements are attributed to the pozzolanic activity of the ashes and the reinforcing effect of nylon fibers. The compressive strength also showed significant gains at 7, 28, and 56 days of curing. Utilizing these waste products promotes environmental sustainability and reduces waste. This research demonstrates the potential of agro-industrial by-products and recycled fibers to produce eco-friendly concrete with enhanced mechanical properties. Further studies are recommended to assess the long-term durability and environmental impacts of these innovative composites.
