The Research on Sintering Behavior of the Lightweight Aggregate Utilizing Reservoir Sediments

摘要

Taiwan Shi-Men Reservoir sediments were used to investigate the expansion mechanism of lightweight aggregate under high temperature sintering processes. The fundamental properties of reservoir sediment and the effects of temperature and time during the sintering process are obtained. Experimental results show that the Shi-Men Reservoir sediment is a very good raw material to be the production of lightweight aggregate. The controlling of the temperature and time during the sintering processes has significant effect on the particle density and absorption of the lightweight aggregate. The feasibility of the major expanded material in reservoir sediments may be due to the decomposition of the carbonate, the organic matter and crystallization water.
