A large quality of sludge is generated each year from water treatment plants in India. Disposing the sludge to the nearest water course is the common practice in India. Disposing rise, the aluminum concentrations in water and consequently in human bodies. This practice has been linked to occurrence of disease due to Landfill disposal of the sludge is impractical because of high cost of transportation and depletes the capacity of landfill. The use of sludge in construction industry is considered to be the most economic and environmentally sound option and also other technically feasible alternative for sludge disposal similar mineralogical composition of clay and sludge. The main objectives are to increase the value of sludge from a water treatment plant and to make a sustainable and profitable disposal. Sludge use as additive material in the concrete mix. This study focused on making bricks, concrete filler and concrete aggregate. The study investigated the use of sludge s partial substitute for Waste may be defined as an unwanted material generated after the manufacturing process from industry, agriculture, or from house hold activity. Waste causes many nuisances in the environment. It produces many types of infection, for human and animal. Dewatered sludge is disposed of by land filling. However, it is not an appropriate solution, due to the land limitation. In addition, the constraint to treat sludge is very high in cost and time-consuming, which is the disadvantage to the responsible parties. Therefore, this study was carried out to utilize that dry sludge produced from the water treatment plants as a concrete additive material. Tests were conducted such as workability test (slump cone test) and compressive strength. As the conclusion, compressive strength of the concrete does not affect to use of sludge.
Keywords: Sludge drying bed free swelling index box shear test, Compressive strength Liquid limit apparatus.
