Low-shrinkage cement-based grouting material as well as preparation method and application thereof
The invention discloses a low-shrinkage cement-based grouting material as well as a preparation method and application thereof. The low-shrinkage cement-based grouting material is prepared by mixing a cement-based grouting dry material and water according to a mass ratio of 100: (9-11), wherein the cement-based grouting dry material comprises the following components in parts by weight: 42-45 parts of a rubber material A; 4-50 parts of aggregate B; 1-7 parts of an additive; and 3-7 parts of a component D. The low-shrinkage cement-based grouting material solves the engineering technical problems that a common cement-based grouting material is poor in early-stage cracking resistance, low in tensile property and the like, the mechanical property and the durability of the low-shrinkage cement-based grouting material are improved to a certain extent, and the low-shrinkage cement-based grouting material is suitable for reinforcing and repairing buildings in high and cold severe areas, and the construction quality of building engineering and normal use in the service period are ensured. The low-shrinkage cement-based grouting material is easy to control the quality of a construction site, and the influence of a mixing process and human factors on the construction quality is reduced.
本发明公开了一种低收缩水泥基灌浆材料及其制备方法和应用，该低收缩水泥基灌浆材料由水泥基灌浆干料和水按100：(9～11)的质量比混合而成；其中，水泥基灌浆干料包括以下按重量份计的组份：胶材A42～45份；骨料B44～50份；外加剂C1～7份；D组分3～7份。该低收缩水泥基灌浆材料解决了普通水泥基灌浆材料早期抗开裂性能差、抗拉性能低等工程技术难题，且该低收缩水泥基灌浆材料在力学性能及耐久性能方面有一定的提升，适用于高寒恶劣地区建筑物的加固、修补，保证建筑物工程的施工质量及服役期的正常使用。该低收缩水泥基灌浆材料易于施工现场的质量把控，降低拌和工艺及人为因素对施工质量的影响。
