Influence of biomass ash and coconut shell in scrap steel fiber reinforced concrete

To develop a sustainable concrete solution, the aggregates and cement in mixture were partially replaced with Cocos nucifera endocarp (coconut shell) aggregate biomass ash (sugarcane bagasse ash) respectively. The fresh hardened properties studied for three types of mixes (i) mix 10-30% replacement (BA), (ii) Bagasse scrap steel fiber 10 - 50% coconut shell aggregate. property is positively influenced by addition ash. With fibers workability reduces 47% when compared to control mix. slump values recorded all within permissible limit. density decreases inclusion which helps reduce dead weight structural elements. mechanical increased 5%, 6% 8% compression, split flexure modes respectively, 10% reinforced concrete. Replacement gravel affects strength properties, but limit application. SEM image analysis showed that porosity content. From test results, it was observed shell, can be effectively used as substitutes ingredients solution.
