The preliminary experimental studies on the effects of two kinds of industrial waste slag of iron tailings and fly ash which have different characteristics on the scumming degree of sea mud sintered perforated brick were carried out in this paper. And the influence mechanism of two kinds of industrial waste slag on the scumming degree of sea mud sintered perforated brick were analyzed combinated with interrelated references. The test and theory analyzed demonstrated that iron tailings have more advantageous factors to alleviate the scumming degree of sea mud sintered brick and fly ash has more disadvantageous factors to enhance the scumming degree of sea mud sintered brick. A vast development world would be provide for the resources reuse of huge dredging sludge come from sea engineering by strengthening the basic study on the scumming resistance technique of sea mud sintered brick.
