摘要
通过抗压强度、抗折强度试验,考察水胶比、砂率和铁尾矿砂掺量对骨料型铁尾矿砂水泥基灌浆料的力学性能影响情况,得到最优的配合比参数。试验结果表明:经过优化配合比,骨料型铁尾矿砂水泥基灌浆料具有与普通骨料型水泥基灌浆料相似的力学性能,说明用铁尾矿砂配制骨料型灌浆料是可行的。
Through compressive strength and bending strength tests, the influences of water-cement ratio; sand ratio and mix amount of iron-tailings on the cement-based coarse aggregate grouting material were studied to get the best mix parameter. The test result indicated that after optimization of mix proportion, the mechanical property of coarse aggregate cement-based iron-railings grouting material was simi[ar to that of normal coarse aggregate cement-based grouting material. It was feasible to compound the coarse aggregate grouting material by iron tailings.
