The dredged material of urban river (DMUR) is of high water content、rich in organic matter、smelly odor and sometimes also contains toxic and hazardous substances. Harmless and resource utilization of DMUR became an important research topic of urban sustainable development. In this study， the dredging project of Nanjing Qinhuai River were taken for example， the DMUR and clay were used as raw materials to produce sintered brick. Percentages of DMUR in raw materials range from 50% to 70% by mass ratio， and brick specimens sintered at kiln temperatures of 1 000℃、1 050℃ and 1 100℃. In order to analyze the impact of clay content and kiln temperature on the sintered specimens， mechanical tests were performed to measure bulk density，weight loss on ignition， shrinkage， water absorption and compressive strength；Chemical compositions and microstructures of the samples were investigated using X-ray diffraction（XRD） and scanning electron microscopy (SEM)，respectively. The results indicate that the kiln temperature has significant effects on sintered specimens， 1 050℃ is the suitable kiln temperature for these specimens; when the clay content is gradually increased， the physical and mechanical properties of sintered specimens gradually increased. Under the optimum preparation condition（DMUR content of 50%， the sintering temperature is 1 050 ℃）， bulk density，water absorption， the linear shrinkage， compressive strength of the sintered bricks were 1.4 g/cm 3，17.28%，-0.5%，12.56 MPa，respectively， meeting the requirements of common bricks. The results of the study have references significant for resource utilization of DMUR.
