Cement-based grouting material taking tailing mud as full aggregate, preparation method and application
The invention discloses a cement-based grouting material taking tailing mud as a complete aggregate, and a preparation method and application of the cement-based grouting material. The cement-based grouting material taking the tailing mud as the complete aggregate is prepared by mixing the following raw materials in parts by mass: 30-60 parts of tailing mud; 30 to 60 parts of a cementing material; 0.4-2 parts of a functional material; 4-25 parts of a composite admixture; and 15-28 parts of mixing water. The cement-based grouting material taking the tailing mud as the complete aggregate, provided by the invention, is used for repairing tiny cavities (holes) and micro cracks in underground spaces. The grouting material has high flowability, can be directly used for grouting micro cavities (holes) and micro cracks by any proper construction process, and is high in construction operability; the trafficability is high, the particle size of the micro aggregate (tailing mud) is small, the micro aggregate can pass through a superfine conveying pipe with the pipe diameter being smaller than 3 mm, and the repairing and repairing requirements of micro holes and micro cracks are met; the tailing mud is used as a complete aggregate, building sand is not used, the cost is low, and the method is worthy of engineering popularization.
本发明公开一种以尾矿泥为全集料的水泥基注浆料、制备方法、应用。以尾矿泥为全集料的水泥基注浆料，由以下质量份的原材料混合而成：尾矿泥30~60份；胶凝材料30~60份；功能材料0.4~2份；复合外加剂4~25份；拌合水15~28份。本发明提供的以尾矿泥为全集料的水泥基注浆料用于地下空间微小空洞（孔洞）修补、微细裂缝修复。该注浆料具有高流动性，可直接以任何合适的施工工艺对微小空洞（孔洞）、微细裂缝进行注浆，施工操作性强；高通过性，微集料（尾矿泥）粒径细，可通过管径在3mm以下的超细输送管，满足微小孔洞和微细裂纹的修补修复需求；可商品化供应，以尾矿泥为全集料，不使用建筑用砂，成本低，值得工程推广。
