Abstract The preparation of cementitious materials by replacing part of the cement with activated coal gangue is of great significance to the cement industry in terms of carbon reduction and coal-based solid waste utilization. For this paper, cementitious material was prepared by firing activated coal gangue under suspension conditions and batching it with limestone powder using Inner Mongolia coal gangue as raw material. The optimal ratio was determined by testing the strength changes of the cementitious material at 3, 7, and 28 days of hydration, and the hydration process and mechanism were explored by combining the… More >
