Abstract :
Aiming at the difficulties in utilization of fly ash from coal gasification, the physical and chemical properties of fly ash were investigated. This research studied recycling utilization on using fly ash as one of cement raw materials for cement clinker. Results showed that fly ash belongs to ordinary solid waste of siliceous and aluminous materials. Cement clinker could be generated by substituting fly ash for shale with different type limestone. The study not only solves the environment pollution problem caused by piling of fly ash, but also realizes its recycling utilization.
