“…As the awareness of the public's environmental protection has been strengthened continuously and the government has gradually paid more attention to the control of the environment pollution, more waterworks have been put in use; the research of the techniques and methods of the sludge treatment has been referred to the agenda. A large number of water supply plants don't have a safe way, it has been a heavy burden for the waterworks, and caused the second-pollution on the environment [1]- [3] Ceramsite, as a kind of lightweight aggregate, attracts more attention for its light body, insulation and environment protection. Currently, clay ceramsite dominates in China, and the source of the clay mostly originates from the plough, this is a route of material which is not consistent with China's national conditions.…”

On the basis of analysis of the component of the sludge from Lingzhuang waterworks and the technological process was studied which use the sludge for raw material to produce the sludge ceramsite. Through a lot of experiments, the several factors affecting the nature of ceramsite were developed and the technological parameters were confirmed. A performance test of the ceramsite shows that when the optimized temperature is 1130°C~1170 °C, the optimized baking time is 5 min, strength of tube pressure of the ceramsite is 8 MPa, bulk density of it is 1200 kg/m3compressive strength of concrete blocks is 40 MPa. So the products could meet the demand on high strength ceremsite. It is gained that the way of waterworks sludge for ceramsite is feasible and can bring certain economical profits, social profits and environmental profits. The products can be used widely to load bearing structure in construction profession.
