Utilization of Industrial Sludge and Quarry Dust in Manufacturing of Bricks
Dr. B M Patil,  Mr. S.B. Bhutekar
Sewage sludge refers to the residual, semi solid material that is produced as a by-product during sewage treatment of industrial or municipal Waste water. Sludge obtained from activated sludge process was used. This Sludge was processed and was then dumped so the odour was impressively reduced. Dumping sludge along with the fly ash used as an ingredient in making of burnt clay bricks and will test the strength of these sludge burnt clay bricks. This paper presents the results of the utilization of dried sludge and quarry dust as brick making materials. The different slabs of percentages of dried sludge that can be mixed with quarry dust and fly ash for brick making are 20%,30% and 40% for sample 1,2 and 3 respectively. The standard compressive strength of the bricks is 10.5N/mm2 and 7 N/mm2 for first and second class brick respectively. The study evaluated the suitability of the use of sludge as partial substitute for clay in brick manufacturing. In this study, three different proportions of dry sludge, quarry dust and fly ash are experimented and evaluated its feasibility as building material with minimum required strength. This study also emphasized on casting of light weight brick by adopting the best possible proportions without compromising with the minimum required compressive strength.
