Abstract: Coal gangue is a solid waste produced in the process of coal mining and processing. It is an effective way to apply it to cement based materials. This paper summarizes the evaluation methods of calcined coal gangue powder activity at home and abroad, such as intensity evaluation method, pozzolanicity test method and modern analysis and test method (XRD, IR, NMR and ICP-AES). Aiming at the main problems existing in the research and application of calcined coal gangue active powder material in cement based materials, the key points for their application in practical engineering are analyzed and elucidated. In order to accelerate the utilization of coal gangue in cement based materials, some reference suggestions are put forward.
