Paper Title:
Influence on Activation Property of Calcined Coal Gangue by [SO4]2+
  Abstract

Coal gangue and limestone were used as raw materials with fluorite and gypsum as the mineralizer. The activation mechanism of calcined coal gangue with calcium and the pore structure of its hydrating slurry are discussed. The experimental results show that during calcinations F- and [SO4]2- come into the framework and react deeper with CaO at 850-950°C to create hydraulic-activity C12A7 and C2S. Pore structure analysis of the hydrating slurry indicates that adding gypsum and fluorite into coal gangue is more propitious to strengthen the slurry and optimize the pore distribution than only of gypsum.
