Paper Title:
Properties and Sintering Mechanism of Lightweight Sludge-Flyash-Clay Ceramics
  Abstract

This study investigated the properties of lightweight sludge-flyash-clay ceramic by different sintering temperature. Different ratios of dry sewage sludge and fly ash with 50 wt% of clay were mixed and pressed into raw pellets. After drying and preheating treatment, the raw pellets were sintered at temperatures ranging from 1050 to 1150 °C, in 25 °C increments for 10 min. The physical properties (bulk density, grain density, water absorption and rate of expansion) were the indexes used to determine the technical parameters for the preparation of lightweight sludge-fly ash ceramic pellets. The results suggested that temperature was the key control factor of sintering process, and 1150 °C was the starting point of the bloating reaction. In the case of a small fraction in the raw material configuration, the mass ratios of sludge to fly-ash had little effect on the properties.
