Construction and demolition activities in India contribute significantly to the generation of waste debris, with an annual output of approximately 10-12 million tons. Although retrievable materials like bricks, wood, metal, and tiles undergo recycling in the country, a major portion of the waste, specifically concrete and masonry waste (constituting over 50% of the total), remains recycled. Despite occasional regulatory efforts, the lack of a comprehensive manual for effective Debris management exacerbates the situation. This presentation represents a pioneering study aimed at laying the groundwork for the development of a practical manual addressing C&D waste management. It specifically focuses on processed concrete fine aggregates (RFA) obtained from C&D waste and explores their application in plaster construction. In addition to providing a concise overview of the engineering properties of processed aggregates, the study offers insights into the impact of these aggregates on both the fresh and hardened properties of concrete and plaster. The research demonstrates that processed aggregates sourced from on-site tested concrete specimens exhibit favorable qualities, contributing to the production of high-quality concrete. This has the caliber to significantly mitigate environmental pollution stemming from construction and demolition waste. Notably, one promising avenue for the utilization of waste concrete is in plastering applications. The plastering process typically involves substantial quantities of sand, cement, and water, which, if not managed properly, can have adverse environmental effects. Alternative approaches may lead to undesirable outcomes and increased life cycle costs.
