Graphite tailing roadbed stabilizing material and preparation method thereof
The invention discloses a graphite tailing roadbed stabilizing material and a preparation method thereof. The preparation method comprises the following steps: dehydrating and drying graphite tailings, grinding and grading, and adjusting the size of a grading screen for screening; the preparation method comprises the following steps: mixing inorganic binding materials according to a ratio, putting the graphite tailings into stirring equipment, uniformly stirring, adding water, fully stirring and mixing to obtain a mixture, putting the mixture into a forming mold, applying pressure to the forming mold, after upper and lower pressing columns at two ends of the mold completely enter the mold, maintaining the pressure, reversely applying the pressure, and demolding to obtain the graphite tailings composite material. According to the graphite tailing roadbed stabilizing material prepared through the method, the optimal water content is 16.8%, the maximum dry density is 1.70 g/cm < 3 >, the 90-day compressive strength reaches 8.51 MPa, and the graphite tailing roadbed stabilizing material is suitable for being used as a roadbed stabilizing material. The method provides a suitable path for reduction and resourceful treatment of the graphite tailings, and improves the utilization rate of wastes.
本发明公开了一种石墨尾矿路基稳定材料及其制备方法,包括:将石墨尾矿脱水干燥,进行研磨分级,调整分级筛网尺寸进行筛选;将无机结合料按比例进行混合,再将石墨尾矿一起置于搅拌设备中,搅拌均匀后,加水,充分搅拌混合,得到混合料置于成型模具,向成型模具施加压力,待模具两头上下压柱全部进入模具内,保压,反向施压进行脱模,制得路基稳定材料试件置于室内自然环境下,静置养护,得到石墨尾矿路基稳定材料,本发明的方法制得的石墨尾矿路基稳定材料最佳含水率为16.8%,最大干密度为1.70g/cm3,其90天抗压强度达到8.51MPa,本发明为石墨尾矿的减量化、资源化处理提供了适宜的路径,提高了废弃物的利用率。
