Preparation method of high-permeability plugging cement slurry
The invention belongs to the technical field of concrete processing and manufacturing, and particularly relates to a preparation method of high-permeability plugging cement slurry, which is prepared from the following raw materials in parts by weight: 70 to 85 parts of portland-pozzolana cement, 17 to 33 parts of S95-grade mineral powder, 75 to 90 parts of fly ash, 70 to 90 parts of fine sand of 70 to 100 meshes, 15 to 20 parts of polypropylene fiber or nylon fiber, 10 to 15 parts of carbon fiber, 13 to 25 parts of hydrogel, 18 to 27 parts of mortar reinforcing agent and 60 to 110 parts of clear water. The prepared cement slurry has the advantages of scientific and reasonable formula, strong permeability, high bonding strength, strong bonding force, stable performance and the like, the cement slurry is fully stirred in a vacuum environment, and all the raw materials are uniformly mixed together, so that the use effect of the cement slurry is improved, the plugging effect of building cracks is improved, the impermeability and durability of concrete are effectively improved, and the service life of the concrete is prolonged. The construction quality is improved, the production cost and the construction cost are reduced, the service life of a building is prolonged, and good economic benefits and social benefits are achieved.
本发明属于混凝土加工制造技术领域，具体涉及一种高渗透性堵漏用水泥浆料制备方法，其各原料重量组份为：火山灰质硅酸盐水泥70～85份、S95等级矿粉17～33份、粉煤灰75～90份、70‑100目细砂70～90份、聚丙烯纤维或尼龙纤维15～20份、碳纤维10～15份、水凝胶13～25份、砂浆增强剂18～27份和清水60～110份；制得的水泥浆料配方科学合理，产品渗透性性强、粘合强度高、粘结力强、性能稳定等优点，水泥浆料真空环境下充分搅拌，各原料均匀的混合在一起，改善水泥浆料的使用效果，提升建筑物裂缝的封堵效果，有效地提高混凝土的抗渗性和耐久性，提高施工质量，降低生产成本和施工成本，增加建筑物的使用寿命，具有良好的经济效益和社会效益。
