In order to improve the construction efficiency and the utilization rate of fine grained tailings, cement of different mass ratios was mixed with fine tailing slurry of which the mass concentration was set to be 40%. Grouting test of geosynthetic tubes was carried out to explore the influence of cement content on the grouting characteristics of geosynthetic tubes. According to the experimental results, the addition of cement as curing agent in the fine tailings mortar can improve the water permeability and sand retention of the geosynthetic tubes. The grouting time and the density of mortar discharging decrease with the increase of the cement content. The quantity of single grouting and single discharge decreases exponentially with the increase of time. The discharge is concentrated in the first two hours, dominated by hydrostatic pressure, and after that, the discharge is dominated by consolidation extrusion due to the dead weight of the fine tailings. The drainage rate, drainage efficiency and sand retention rate increase with the increase of cement content. The drainage efficiency and sand retention rate can be selected as the indexes to evaluate the permeability and sand retention of geosynthetic tubes, and the optimal cement content is determined as 3% after comprehensive consideration of construction efficiency, utilization rate of fine tailings and construction cost.
