Brick is one of the most important and widely used construction material due to its properties. Now-adays many attempts have been made to incorporate different wastes into the production of bricks. In many countries, Sludge waste is a serious problem due to its high treatment costs and the risks to environment and human health. The sludge generated in various treatment systems around the world is discharged into the nearest watercourse. Thus, rather than disposing, the use of sludge in producing constructional elements is considered to be the most economic and environmentally sound option. The properties of STP Sludge and Fly Ash is extremely close to brick clay so, it could be a potential substitute for clay bricks. In this study the bricks were produced with sewage sludge additions ranging from 10, 20, 30, 40 and 50 % by dry weight and compared the produced brick with conventional brick. The manufacturing of bricks is done by moulding clay in rectangular blocks of uniform size and then by drying and burning these blocks. Burnt clay bricks have good resistance to moisture, insects and erosion and create a good environment. Their cost is comparatively low and have medium to high compressive strength. Results of the tests performed indicated that the sludge proportion and the firing temperature were the two key factors determining the brick quality. Results showed that the loss of brick weight after ignition was mainly attributed to the organic matter content in the sludge being burnt off during the firing process. Hence sludge can be used as a replacement for clay, soil in manufacturing of bricks. Also from this investigation we can solve disposal problems completely and also construct an economical structure with easy designing.
