Coal-Based Cementitious Material

This coal-based solid waste new material is an innovative material developed for regions rich in coal resources in northern China, addressing the challenges of solid waste treatment and resource utilization during coal development and utilization. This material is produced by processing solid waste from power plants, coal chemical plants, and smelting plants with a small amount of additives. Crushed coal gangue is used as filling aggregate for mine filling, achieving not only reasonable disposal and resource utilization of coal-based solid waste but also addressing the top-sealing rate issue in mine filling, reaching a higher top-sealing rate. This approach promotes environmental protection and enhances resource utilization efficiency.
