Feasibility of Using Coal Ash for the Production of Sustainable Bricks

In this research study, environmentally friendly unburnt coal ash (CA) bricks were investigated as an alternative to conventional burnt clay bricks. various physical and mechanical properties of CA investigated. The prepared by using 60% 10% lime weight. these bricks, varying cement contents (5%, 10%, 15%), sand (10% quarry dust (5% 10%) weight used. A forming pressure 29 MPa was applied through automatic control system either for 3 s or 6 s. moist cured 28 days. experimental results exhibited that with cement, sand, subjected the highest compressive strength 19 flexural 2.1 MPa. reduced water absorption, efflorescence, lower per unit area than cost comparison are cost-effective compared
