In the recent times, it is seen that there is steep increase in the sludge production due to the rapid growth of urban areas and consequent generation of waste.; as a result of which the safe disposal of the same has become a challenge in terms of cost and availability of landfills and dump yards. In an attempt of finding possible solutions to this problem, this paper focuses on utilizing sludge in a productive way ,which may facilitate resolving the problem of disposal of industrial sludge as well as giving an effective outcome to use it as a cost effective construction material .The air dried sludge from the city municipal sewage treatment plant was collected and tested for its geotechnical properties along with that of clay and fly ash which are the main components of conventional brick .Different proportions of dried sludge was used as a substitute for clay along with fly ash. To find out the performance of the brick along with its strength, the sludge proportions were varied out from 5% to 20%. Two major tests for the bricks viz. compressive strength test and water absorption test were conducted on the bricks having varying sludge proportions to obtain the optimum proportion at which highest strength is obtained as compared with those of conventional bricks. From the test results it could be inferred that, a sludge percentage varying between 5-10%, yields the best results in terms of compressive strength and other parameters as per Indian Standards. This paper thus brings out the importance of management of industrial sludge as well as its suitability in using as a brick additive material; thereby offering a possible way of safe disposal of the sludge.
