The collected sludge was dried to reduce its moisture content and then sieved to remove the dusts present in that. The sieved sludge was then mixed with the concrete cubes and mortar cubes in 4%‚ 8% and 12%. The cast specimens were then cured for 7 days‚ 14 days and 28 days. The cured specimens were tested for its compressive strength. Then hollow blocks‚ pavement blocks and mortar bricks were cast and cured
