黄河水利科学研究院泥沙利用研究团队秉承“创新、环保、兴利、持续”的务实理念,在胶凝技术、成套技术装备、煤矿绿色充填开采技术等方面取得了若干成果,拓展了泥沙资源的利用方向。泥沙资源利用胶凝技术:先后研发了水泥基胶凝技术和非水泥基胶凝技术。主要原料为黄河泥沙,用量占70%以上;掺和料为粉煤灰、尾矿粉、炉灰等具有一定活性的工业废料;胶凝激发材料为水泥、石灰等。产品抗压强度控制
Yellow River Hydraulic Research Institute of sediment utilization research team adhering to the “innovation, environmental protection, Xingli, sustained ” pragmatic philosophy, in the gelation technology, complete sets of technical equipment, mining green filling mining technology has made some achievements, expanding Use of sediment resources. Sediment utilization gelling technology: has developed a cement-based gelling technology and non-cementitious gelling technology. The main raw material for the Yellow River sediment, the amount accounted for more than 70%; admixture for fly ash, tailings, ashes and other have some activity of industrial waste; gelling excitation materials for cement, lime and so on. Product compressive strength control
