烧结温度对陶粒性能的影响研究

s the by-products of wastewater treatment, the output of sewage sludge increases greatly with the large scale growth of wastewater treatment. Sludge disposal has been one of serious environmental concerns, it is easy to cause secondary pollution if mishandled. In this paper, the effects of sintering temperature on the properties of raw materials and the physical properties of lightweight aggregates were studied. The results shown that when temperature is higher than 950℃, the crystal can reach the steady state. When sintering temperature reaches 1100℃, lightweight aggregates with desired physicochemical properties can be attained.
