Iron tailing sand grouting material for concrete filled steel tube grouting and preparation method of iron tailing sand grouting material
The invention discloses an iron tailing sand grouting material for concrete filled steel tube grouting and a preparation method of the iron tailing sand grouting material, and relates to the technical field of concrete. The iron tailing sand grouting material is composed of an iron tailing sand grouting composition and water, raw materials of the iron tailing sand grouting composition comprise, by mass, 45% of cement, 9% of a mineral admixture, 45% of fine aggregate and 1% of a composite functional material, and the composite functional material is composed of an expanding agent, a water reducing agent and a retarder. The grouting material disclosed by the invention is good in fluidity, high in early strength, micro-expansive and good in binding property, can be used as a steel tube concrete grouting material, and is particularly used for void grouting of a steel tube concrete structure.
本发明公开了一种钢管混凝土注浆用铁尾矿砂灌浆料及其制备方法，涉及混凝土技术领域。本发明铁尾矿砂灌浆料由铁尾矿砂灌浆组合物和水组成，其中，铁尾矿砂灌浆组合物的原料按照质量百分含量计包括如下组分：水泥45％、矿物掺合料9％、细骨料45％及复合功能材料1％，其中，复合功能材料由膨胀剂、减水剂和缓凝剂组成。本发明的灌浆料流动性好、高早强、微膨胀、结合性好，可用作钢管混凝土注浆材料，尤其是用于钢管混凝土结构脱空注浆。
