Cement-based rapid repairing material and construction process thereof
The invention relates to the technical field of cement-based inorganic materials, in particular to a cement-based rapid repairing material and a construction process thereof. The repairing material comprises the following raw materials in parts by weight: 60 to 80 parts of Portland cement, 20 to 28 parts of Secar71 cement, 14 to 25 parts of quartz sand, 2 to 5 parts of bone glue, 1.2 to 2.0 parts of polypropylene fibers, 1.5 to 2.5 parts of basalt fibers, 25 to 35 parts of a mixed filler, 0.03 to 0.06 part of a water-retaining agent, 1.2 to 1.8 parts of a function enhancer, 0.6 to 1.2 parts of a water reducing agent, 0.5 to 0.8 part of a compound exciting agent, 0.6 to 0.9 part of an organic silicon defoaming agent, 0.4 to 1.0 part of a retarder and 20 to 30 parts of water. The cement-based rapid repairing material provided by the invention not only can accelerate the hydration speed of cement, but also can promote the early strength of concrete, so that the early strength of the concrete is effectively improved; in addition, the early strength, the density and the anti-freezing property of the repairing material can be effectively enhanced; and the quality of the repairing material is effectively improved.
本发明涉及水泥基无机材料技术领域，具体为一种水泥基快速修补材料及其施工工艺；包括以下重量份原料组成：60～80份硅酸盐水泥、20～28份Secar71水泥、14～25份石英砂、2～5份骨胶、1.2～2.0份聚丙烯纤维、1.5～2.5份玄武岩纤维、25～35份混合填料、0.03～0.06份保水剂、1.2～1.8份功能增强剂、0.6～1.2份减水剂、0.5～0.8份复配激发剂、0.6～0.9份有机硅消泡剂、0.4～1.0份缓凝剂及20～30份水；本发明所提供的水泥基快速修补材料不仅能加速水泥水化速度，也能促进混凝土早期强度，有效地提高混凝土早期强度；再者，其还能有效地增强修补材料的早期强度、致密度及抗冻性能；有效地提高了修补材料的品质和质量。
