| Summary: Increase in population, life standards and industrial activities has caused much more necessity of obtaining drinking water. Processing and eliminating the drinking water treatment sludge, occuring by depending on this obligation and the inevitable secondary product of treatment stages, are becoming very important problems day by day. It is known that this waste negatively affects nature and living being by polluting air, soil and water when it directly discharges environment. Utilization from activated drinking water treatment sludge, obtained drinking water treatment sludge by burning at different temperatures, and drinking water treatment sludge in cement was investigated because waste must be recycled. In this study, firstly, phycical, chemical and mineralogical characteristics of drinking water treatment sludge , gaining from Trabzon drinking water treatment plant, was determined. Then, this waste was burnt at different temperatures (500, 600 and 700 oC) and changing composition and characteristics of it were found out. And then, cement mortar, including drinking water treatment sludge and activated drinking water treatment sludge at different percentage (%5, 10, 15 and 20), was produced and compressive strengths, setting, volume expansion of them were measured 1,2,7,and 28 days later. Obtained findings were compared with both samples, blended cements at various addition levels, and checking samples according to Turkish standards. In conclusion, drinking water treatment sludge and activated drinking water treatment sludge seemed to be suitable to produce blended cements at 5-10 % addition levels.
