Abstract

The large amount of sludge is generated in paper manufacturing plants make necessary the initiation of reuse to reduce the sludge generated as a waste, such as its use in brick manufacturing. If sludge is disposed, it effects to environment in various ways. In this paper, the materials used for brick manufacturing are clay (mix of red and black clay), paper sludge, rice husk and fly ash. The physical and chemical properties of these materials are studied. The experiments have been conducted on hand moulded bricks in various mix proportions. In this, all bricks have been dried in natural conditions and lab tests are conducted as per IS Standards. The compressive strength satisfies the need of IS Code wherein, sludge added in brick manufacturing with 20% additionally and partial and fully replacement of rice husk with 10 and 20% of sludge. The water absorption of bricks also satisfies as per codes.
