In many countries, sludge is a serious problem due to its high treatment costs and the risks to the environment and human health. The sludge presents an increasingly difficult problem to cities of all sizes because of the scarcity of suitable disposal sites, increasing labour costs, and environmental concerns. The study investigated the use of sludge incorporated with clay. In this study, bricks were produced with sewage sludge additions ranging from 10, 20, 30, 40 and 50 % by dry weight respectively and compare produce brick with regular brick. After the testing of all the brick samples for the compressive strength it comes to know that bricks made up of sludge up to 10 percent can be used for the construction of all the structures as it has the satisfactory results in the form of the hardness. Also from this investigation, we can solve disposal problem completely and also construct and economical structure with easy designing.
