The present invention provides a simple facile and effective process route for the production of high performance civil engineering construction products using waste foundry sand (WFS) with suitable thermosetting aqueous amino resin polymeric binder. The amino resin binder capable of compatible with different substrates are specifically synthesized using appropriate cost competitive chemical precursors at optimized experimental conditions and formulated with varying nature of functional chemical additives, modifiers and reinforcements. The present invention offers a facile route for the development of synthetic amino resin polymeric binder with required properties suitable for converting waste foundry sand (WFS) in to value added civil engineering construction products viz. tiles, bricks, pavers and panels. The construction products fabricated using WFS with amino resin aqueous polymeric binder cured at appropriate temperature conditions possess excellent strength properties suitable for construction applications. Further, the specimens fabricated have been immersed in distilled water for a period of three months and their physicochemical and strength properties have rechecked and there were no significant changes in their properties. The porous nature of the construction product developed in the present invention also contributes to water harvesting application and alleviate problems due to water logging. The present invention is considered to be an outstanding method of environmentally friendly solid waste management and conversion of waste foundry sand into industrially useful value added cost competitive construction products.
