Optimizing Concrete Properties with Stone Dust and Banana Peel Admixture

Concrete’s widespread use has intensified the demand for river sand, leading to scarcity and environmental concerns. This project investigates stone dust and brick crusher dust as sustainable fine aggregate replacements in M35 concrete. Stone dust, a byproduct of quarrying, and brick crusher dust, from construction waste, offer viable alternatives. The study aims to evaluate their impact on concrete strength and workability. Replacing river sand with stone dust (0%, 50%, 60%, 70%) demonstrated a 10% increase in compressive and tensile strength up to a 60% replacement. Additionally, brick crusher dust shows potential as a cost-effective, eco-friendly fine aggregate. Furthermore, dried banana peel powder (DBPP) is explored as a natural admixture. Its cellulose content may enhance workability and reduce shrinkage, offering a sustainable alternative to synthetic additives. However, proper treatment is essential for durability. This research highlights the effectiveness of stone dust and brick crusher dust as fine aggregate replacements, maintaining design strength while promoting waste utilization. The incorporation of DBPP presents an innovative approach to sustainable concrete production. This project aims to contribute to eco-friendly construction practices by demonstrating the viability of these alternative materials
