Study on Activation of Added-Calcium-doped Coal Gangue and Mechanism of Activity Evaluation

SONG Xuyan~1, LI Dongxu~2, GONG Chenchen~2, HAN Jingyun~1(1 Department of Civil Engineering, University of Science and Technology of Suzhou, Suzhou 215011;2 College of Material Science & Engineering,Nanjing University of Technology,Nanjing 210009)  
Lime absorption, through determining Ca(OH)_2 content, pozzolanic performance of added-calcium-doped coal gangue is studied in the condition of no excitant or NaOH of different density. The research of structural level for activity evaluation process of various kinds of added-calcium-doped coal gangue is made by means of X-ray diffraction (XRD) and method of mercury in trusion poremeasurement (MIP) etc. The experiment can approve that the change on structural characteristic of hydration process of every composite system is consistent basically with that of Ca(OH)_2 content.
