Abstract

An increasing need for sustainable construction materials has prompted the investigation of alternate cementitious and fine aggregate substitutes. This study investigates the partial substitution of cement with bagasse ash, river sand with waste foundry sand, and the addition of steel fibres to enhance mechanical and durability characteristics. The optimum blend was determined to be 15% bagasse ash, 20% waste foundry sand, and 1% steel fibres. Fibres were incorporated to enhance sulphate resistance, reduce water absorption, and improve fracture resistance. The modified concrete mixes were confirmed to be of acceptable to excellent quality by the Ultrasonic Pulse Velocity (UPV) results. The results indicate that sustainable concrete can attain improved strength and durability without forfeiting workability by incorporating industrial by-products and fibre reinforcement © 2025 The Authors.
