High-speed rail concrete base repairing material and repairing method thereof
The invention discloses a high-speed rail concrete base repairing material and a repairing method thereof, and belongs to the technical field of building repairing materials and repairing methods. The repairing material is formed by compounding and stirring magnesium ammonium phosphate cement, an additive, a mineral admixture, aggregate and fiber in a water environment. The repairing material has the advantages of high early strength and high strength, and realizes rapid repairing in the window period of the high-speed rail; the binding power is strong and close to the linear expansion coefficient; the repairing material has good durability, and can overcome the defects that an organic repairing material is easy to age and short in service life; the defect of brittle failure of a cement-based material is overcome; according to the repairing method, a nanometer permeable material is adopted to seal and reinforce a degraded concrete base layer, the defect that other repairing materials cannot improve the performance of base layer concrete is overcome, and the binding power of the base layer and the repairing layer is enhanced; and independent packaging is adopted to meet the requirement for short window period time, repairing of the high-speed rail concrete base is efficiently completed, and the material and the method are suitable for large-area popularization.
本发明公开了一种高铁砼基层修补材料及其修补方法，属于建筑修补材料及修补方法技术领域，修补材料由磷酸铵镁水泥、添加剂、矿物掺合料、骨料和纤维在水环境下复合搅拌而成，本发明的修补材料具有以下优点：具有高早期和高强特性，可实现在高铁窗口期内的快速修补；粘结力强和线膨胀系数接近；具有良好的耐久性，可克服有机修补材料易老化、使用寿命短的缺陷；克服水泥基材料脆性破坏的缺陷；修补方法采用纳米渗透型材料可对劣化混凝土基层密封和补强，克服了其他修补材料无法改善基层混凝土性能的缺陷，且使基层和修补层的粘结力增强；采用独立包装适应窗口期时间短的需求，高效完成高铁砼基层的修补，适合大面积推广。
