Utilization of Agro-Industrialwaste for Sustainable Brick Production

This study explores the feasibility of manufacturing eco-friendly bricks using dairy sludge as a primary raw material, supplemented with construction waste and fly ash as admixtures. Dairy sludge, a by-product of milk processing industries, presents significant environmental disposal challenges due to its high organic and moisture content. When appropriately treated and combined with pozzolanic materials like fly ash and inert construction debris, it can be transformed into a viable brick-making component. The experimental methodology involved varying the proportions of dairy sludge, fly ash, and construction waste to assess the optimal mix for compressive strength, water absorption, durability, and thermal conductivity. Preliminary results indicate that bricks produced from this composite mix demonstrate satisfactory mechanical and thermal properties comparable to conventional clay bricks, while significantly reducing carbon emissions and resource depletion and also pave the way for cost-effective and eco-conscious construction practices.
