Self-compacting and curing iron tailing fine sand concrete grouting material and preparation method thereof
The invention discloses a self-compacting and curing iron tailing fine sand concrete grouting material and a preparation method thereof, and belongs to the technical field of grouting materials. The iron tailing fine sand concrete grouting material capable of being self-compacted and cured is prepared from 15 to 30 parts of cement, 20 to 40 parts of silty clay, 20 to 40 parts of iron tailing fine sand, 20 to 60 parts of water, 0.5 to 5 parts of curing agent and 0.5 to 3 parts of additive. The cement, the silty clay, the iron tailing fine sand, the curing agent and the additive are mixed in proportion and stirred, water is added, then stirring is conducted again, and the iron tailing fine sand concrete grouting material is obtained. The grouting material has the properties of self-leveling, curing, self-compacting and the like, and solves the common quality problems that a narrow underground space is difficult to backfill and compact, and the grouting material is easy to settle after backfilling and the like. Meanwhile, silty clay and iron tailing fine sand are used as grouting adulteration materials, and the purposes of being economical, applicable, energy-saving and environment-friendly are achieved.
本发明公开了一种可自密实固化的铁尾矿细砂混凝土注浆材料及其制备方法，属于注浆材料技术领域。本发明的可自密实固化的铁尾矿细砂混凝土注浆材料，包括水泥15‑30份、粉质粘土20‑40份、铁尾矿细砂20‑40份、水20‑60份、固化剂0.5‑5份、外加剂0.5‑3份。本发明将水泥、粉质粘土、铁尾矿细砂、固化剂和外加剂按比例混合并搅拌，掺入水后再次搅拌，即得所述铁尾矿细砂混凝土注浆材料。该注浆材料具有自流平、可固化、自密实等性能，解决了狭窄地下空间难回填、难压实、回填后易沉降等质量通病。同时，本发明利用粉质粘土和铁尾矿细砂作为注浆掺加材料，达到了经济适用、节能环保的目的。
