Based on the physical and chemical properties of sludge and construction waste, construction rubbish, sludge or river sediment were used as base stock to prepare a well kind of waterproof insulated high strength and lightweight foaming ceramic plate, and the effects of firing condition, solid phrase including aggregate and glass fragment, animal foaming agent, bentonite on the foaming tendency and properties such as water absorption rate, porosity, density and compressive strength were explored. The results showed that under the optimal formula and firing conditions including the combined aggregate of construction waste and sludge of 70%, glass fragments of 20%, animal protein foaming agent of 5%~7%, bentonite of 5%~7%, and under preheating temperature of 700 ℃, preheating time of 40 min, sintering temperature of 1 200 ℃, sintering time of 30 min, the best foaming ceramic property was obtained such as the water absorption rate of 1.62%, porosity of 70.12%, the compressive strength of 5.12 MPa, the bulk density of 0.48 g/cm3. The product performance is better than the relevant national standards.
