High-performance iron tailing sand sleeve grouting material for prefabricated buildings and preparation method of high-performance iron tailing sand sleeve grouting material
The invention discloses a high-performance iron tailing sand sleeve grouting material for prefabricated buildings and a preparation method of the high-performance iron tailing sand sleeve grouting material, and relates to the technical field of cement-based grouting materials. The grouting material is composed of a binding material (formed by compounding ordinary Portland cement and sulphoaluminate cement), a fine aggregate (composed of natural sand and iron tailing sand), a mineral admixture (composed of fly ash and superfine slag) and a water reducing agent; and the proportion is simple, the complexity of the actual construction process is reduced, and the problem that in an existing grouting material preparation process, due to the use of various additives, the performance of a grouting material is not stable is solved. The grouting material adopts the continuous grading iron tailing sand to replace natural sand, so that a large amount of solid waste is really consumed while the performance of the cement-based grouting material is ensured, and the grouting material has good social and economic benefits.
本发明公开了一种用于装配式建筑的高性能铁尾矿砂套筒灌浆料及其制备方法，涉及水泥基灌浆料技术领域。本发明由胶凝材料（普通硅酸盐水泥与硫铝酸盐水泥复配而成）、细骨料（天然砂和铁尾矿砂组成）、矿物掺合料（粉煤灰和超细矿渣）和减水剂组成，配比简单，降低了实际施工过程的复杂性，解决了现有灌浆料制备过程因使用多种外加剂，导致的灌浆料性能的不稳定缺陷。灌浆料采用连续级配铁尾矿砂替代天然砂，在保证水泥基灌浆料性能的同时，真正意义的消耗了大量固体废弃物，具有良好的社会和经济效益。
