Sulphoaluminate cement-based repair material with overspeed setting and early strength as well as preparation method and application of sulphoaluminate cement-based repair material
The invention discloses a sulphoaluminate cement-based repair material with overspeed setting and early strength as well as a preparation method and application thereof, and belongs to the technical field of concrete. The sulphoaluminate cement-based repair material is prepared from the following raw material components: mixed powder consisting of iron powder particles and sulphoaluminate cement, and water, in the mixed powder, the volume ratio of the iron powder particles to the sulphoaluminate cement is 2.5: 97.5-1: 9; the mass ratio of the water to the mixed powder is (0.3: 1)-(0.6: 1). The raw material components are low in cost and wide in source, and by controlling the specific proportion of the components, the material has the advantages of overspeed setting, early strength and scouring resistance in a flowing water environment. The preparation method of the repair material has the advantages of convenient steps, simple operation and no need of complex personnel training. When the material is used for plugging engineering, the material has excellent adaptability under the construction conditions of various plugging engineering, and the application range of the material is expanded.
本发明公开了一种超速凝早强的硫铝酸盐水泥基修复材料及其制备方法和应用，属于混凝土技术领域。硫铝酸盐水泥基修复材料的原料包括如下组分：铁粉颗粒与硫铝酸盐水泥构成的混合粉末、水；混合粉末中，铁粉颗粒与硫铝酸盐水泥的体积比为2.5:97.5～1:9；水与混合粉末的质量比为0.3:1～0.6:1。以上原料组分成本低廉、来源广泛，本发明通过控制组分间的特定比例，使材料在动水环境下具备超速凝早强、耐冲刷的优点。修复材料的制备方法的步骤便捷、操作简单，无需复杂的人员培训。用于封堵工程时，在各类封堵工程的施工条件下具有极佳的适应性，拓展了该材料的应用范围。
