Abstract：
Sludge at concrete mixing plant could be used as concrete aggregate to increase its utilization. Cement mortar test is carried out by using sludge to replace powdered coal ash, to evaluate the activity of sludge and research the influence of sludge on mechanical property and durability and durability of concrete. It is found that sludge has relatively low activity and that it will not produce influence on compression strength of concrete when its content replacing powdered coal ash is not more than 30%.
