摘　　要：以河道清淤的淤泥为研究对象,通过控制不同的含水率及不同的淤泥掺量来进行淤泥制砖的试验研究。主要通过测试试样的抗压强度、吸水率、烧成收缩率来表征试样的相关性能。试验结果表明:试验采用的淤泥掺量可达到45%,利用淤泥制砖的烧结温度应控制在850~900℃。In this paper, the river silt is the research object,and the experimental research on sludge briquette is carried out by different water content control and different sludge incorporation quantity. The relevant performance indexes of the test specimens are characterized mainly by measuring the compressive strength,water absorption and sintering shrinkage of the samples. It is concluded that the sludge content used in the test can reach 45%,the brick using river silt sintering temperature should be controlled in 850-900 ℃.

关 键 词：河道淤泥 制砖 抗压强度 吸水率
