Super-early-strength self-sealing type cement-based grouting material and preparation method thereof
The invention discloses a super-early-strength self-sealing type cement-based grouting material and a preparation method thereof, and relates to the technical field of cement-based grouting materials. The material is prepared from 252 to 560 parts of sulphoaluminate cement, 102 to 135 parts of high-alumina cement, 35 to 52 parts of ordinary Portland cement, 23 to 25 parts of gypsum, 34 to 38 parts of fly ash, 90 to 95 parts of superfine mineral powder, 30 to 35 parts of fine sinking beads, 24 to 28 parts of silica fume, 50 to 56 parts of quartz sand, 50 to 56 parts of dried sand and 7 to 8 parts of an additive. As the sulphoaluminate cement, the high-alumina cement and the ordinary Portland cement are adopted in a volume ratio of 5: 3: 2, the super-early-strength self-sealing type cement-based grouting material effectively solves the problems that the existing super-early-strength cement-based grouting material is poor in self-flowability when in use, the self-sealing property is poor, and the grouting effect is poor. The technical problem that cement cannot be completely filled into a gap needing to be repaired due to the fact that the cement is filled into the gap needing to be repaired is solved, the final setting time of the super-early-strength grouting material is effectively prolonged, the super-early-strength grouting material can fully flow into the gap needing to be repaired, the gap is completely blocked, and automatic sealing is achieved.
本发明公开了一种超早强自密型水泥基灌浆材料及其制备方法，涉及水泥基灌浆材料技术领域，其中，材料包括：硫铝酸盐水泥252‑560份、高铝水泥102‑135份、普通硅酸盐水泥35‑52份、石膏23‑25份、粉煤灰34‑38份、超细矿粉90‑95份、精细沉珠30‑35份、硅灰24‑28份、石英砂50‑56份、烘干砂50‑56份、外加剂7‑8份。本发明所述的一种超早强自密型水泥基灌浆材料，由于采用了硫铝酸盐水泥、高铝水泥和普通硅酸盐水泥以体积为5:3:2，所以，有效解决了现有的超早强水泥基灌浆材料在使用时，自身流动性不佳，导致水泥无法完整的填入所需修补的缝隙中的技术问题，进而有效的延长超早强灌浆料的终凝时间，使其能够充分的流入到所需修补的缝隙中，从而将缝隙完全堵住，从而自动进行密封。
