High-carbonization-resistance and high-toughness cement-based repairing material and preparation method thereof
The invention discloses a cement-based repairing material with high carbonization resistance and high toughness and a preparation method of the cement-based repairing material. The cement-based repairing material is prepared from the following components in parts by mass: 600 to 700 parts of ordinary Portland cement, 200 to 300 parts of sulphoaluminate cement, 1000 parts of sand, 60 to 80 parts of gypsum, 3 to 5 parts of a capillary crystalline material, 11.5 to 13.5 parts of a water reducing agent, 5 to 8 parts of a retarder, 17 to 20 parts of fibers and 320 to 350 parts of water. The preparation method comprises the following steps: firstly, combining the ordinary Portland cement, the sulphoaluminate cement, the gypsum and the capillary crystalline material, then sequentially adding the water, the water reducing agent, the retarder and the polyvinyl alcohol fiber, and then vibrating, inserting and tamping, and laminating and curing to obtain the cement-based repairing material with high carbonization resistance and high toughness.
本发明公开了一种高抗碳化性高韧性水泥基修补材料及其制备方法，水泥基修补材料包括如下质量份数的组分：普通硅酸盐水泥600～700份，硫铝酸盐水泥200～300份，砂1000份，石膏60～80份，渗透结晶材料3～5份，减水剂11.5～13.5份，缓凝剂5～8份，纤维17～20份，水320～350份。制备方法包括先将普通硅酸盐水泥、硫铝酸盐水泥、石膏和渗透结晶材料结合，再依次加入水、减水剂、缓凝剂和聚乙烯醇纤维，随后振动插捣，覆膜养护，得到高抗碳化性高韧性的水泥基修补材料。
