Paper Title:
Effect of Added-Calcium Thermal Activated Coal Gangue on Cement Hydration
  Abstract

Through determining Ca(OH)2 content and chemically combined water content, hydration degree of cement with added-calcium thermal activated coal gangue may be analyzed. Variation of mineral composition during hydration process of system was analyzed by X-ray diffraction(XRD) method. Simultaneously, specific strength index was applied to study pozzolanic effect of activated coal gangue. The results can show high contribution of added-calcium coal gangue calcined at 1050°C for pozzolanic properties and high hydration reaction degree in this kind of activared coal gangue cement system, with fewer Ca(OH)2 content, more chemically combined water content and obviously reduced hydration product Ca(OH)2 at each age.
