Research on Compressive Strength of Brick with Partial Replacement of Fly Ash

Clay fly Ash burnt bricks can be extensively used in all building constructional activities similar to that of common burnt clay bricks. The clay fly ash burnt bricks are comparatively lighter in weight and stronger than common clay bricks. Since fly ash is being accumulated as waste material in large quantity near thermal power plants and creating serious environmental pollution problems, its utilization as main raw material in the manufacture of bricks will not only create ample opportunities for its proper and useful disposal but also help in environmental pollution control to a greater extent in the surrounding areas of power plants. The compressive strength of Fly ash brick increases as the percentage of fly ash added. Increase in compressive strength for 5% to 40% of fly ash in clay bricks are 4.92, 5.085, 5.255, 5.85, 5.95, 6.68, 6.85, 8.58 (N/mm²).
