| 摘 要： | 实验以赤泥、水淬高炉矿渣、脱硫石膏、全尾砂和少量水泥熟料制备出一种新型的膏体和似膏体全尾砂胶结充填材料，通过对体系质量浓度的考察，得出了质量浓度（水胶比）一坍落度、坍落度一强度关系曲线。膏体全尾砂胶结充填料的合适的质量浓度为79．4％～81．9％，所制备的试块60d强度达到4～6MPa；似膏体胶结充填料的合适的质量浓度...

| Abstract: | A new paste and paste-like backfilling material was prepared with red mud,quenched blast furnace slag,desulphurization gypsum,whole-tailings and a little cement clinker.With the different concentration of the slurry,the relationship between mass concentration and slump as well as the relation of slump and strength were obtained.The results of the experiment indicated that the appropriate concentration of the cemented whole-tailings backfilling paste was 79.4%~81.9% and its compressive strength of 60 days wa... |
