Abstract
The inclusion of aggregate geological origin in elastic modulus estimation under draft IS 456:2025 marks a significant shift in RCC design approach. Dr. Dada S. Patil, examines how this move from strength-based to a more material-sensitive approach could influence structural behaviour, serviceability predictions, and overall design accuracy, and highlights the technical, practical, coordination, and contractual challenges in aligning design assumptions with on-site conditions.
