Concrete repair dry-mixed mortar used in corrosion-freeze-thaw coupling environment and preparation method of concrete repair dry-mixed mortar
The invention discloses concrete repair dry-mixed mortar used in a corrosion-freeze-thaw coupling environment and a preparation method of the concrete repair dry-mixed mortar. The concrete repair dry-mixed mortar is prepared from a component A, a component B and a component C in a mass ratio of 1000: 1000: (20-30); the component A comprises sulphoaluminate cement, Portland cement and fly ash; thecomponent B is a mixture of quartz sand of 10-20 meshes and quartz sand of 40-80 meshes; and the component C comprises a water reducing agent, polypropylene fibers, cellulose ether, a chloride ion adsorbent, an air entraining agent, hollow glass beads, lithium carbonate and calcium formate. The concrete repair material prepared from the concrete repair dry-mixed mortar for the corrosion-freeze-thaw coupling environment has a chloride ion adsorption function and a heat preservation function, can effectively solve the problem that the repaired concrete is easily damaged due to the influence of chloride ion erosion and freeze-thaw action in a corrosion-freeze-thaw coupling environment, and has important significance in prolonging the service life of the concrete and improving the safety of the concrete.
本发明公开了一种用于腐蚀‑冻融耦合环境下的混凝土修复干混砂浆及其制备方法。所述的混凝土修复干混砂浆由质量比为1000:1000:20‑30的A、B、C三组分组成；A组分包括硫铝酸盐水泥、硅酸盐水泥和粉煤灰；B组分为10‑20目石英砂和40‑80目石英砂的混合物；C组分包括减水剂、聚丙烯纤维、纤维素醚、氯离子吸附剂、引气剂、空心玻璃微珠、碳酸锂和甲酸钙。由本发明配制的用于腐蚀‑冻融耦合环境下的混凝土修复干混砂浆制得的混凝土修复材料具有氯离子吸附功能和保温功能，能够有效解决腐蚀‑冻融耦合环境下混凝土修复后受氯离子侵蚀和冻融作用影响而易于破坏的问题，对于延长混凝土使用寿命及其安全性具有重要意义。
