Abstract: Through the orthogonal experiment, the activation ingredient of fly ash from coal gangue-fired power plant and ingredient of the gunning material were studied, and the activation mechanism of fly ash was revealed. The microstructure of gunning material was analyzed with SEM image, compared with the SEM image of authentic sample added with raw fly ash. The research results show that the gunning material added with chemical activated fly ash has 9.1MPa and 24.8MPa standard compressive strength at 3d and 28d curing age respectively, which meet with the requirement towards the strength on mining engineering.
