Self-repairing fiber-reinforced ultra-high performance concrete electrical pole and processing method thereof
The invention discloses a self-repairing fiber-reinforced ultra-high performance concrete electrical pole and a processing method thereof. The electrical pole comprises a reinforcement cage, wherein the outer side of the reinforcement cage is coated with self-repairing fiber-reinforced ultra-high performance concrete, and the self-repairing fiber-reinforced ultra-high performance concrete comprises the following raw materials: 40-60 parts of composite glue liquid core fiber, 950-1000 parts of Portland cement, 160-170 parts of rice hull ash, 900-1200 parts of bauxite, 70-90 parts of glass powder, 50-70 parts of polypropylene fiber, 145-170 parts of water, and 40-60 parts of a carboxylic acid water reducing agent. According to the invention, by adding short and fine repairing glue liquid core fibers, when a concrete structure generates cracks, liquid seeps to repair the cracks, so that corrosion and oxidation of reinforcing steel bars can be prevented, regenerating can be performed during damage, and the characteristics of ultrahigh strength, high toughness, high durability, high volume stability and the like are achieved.
本发明公开了一种自修复纤维增强超高性能混凝土电杆及其加工方法，包括钢筋笼，所述钢筋笼的外侧包覆有自修复纤维增强超高性能混凝土，所述自修复纤维增强超高性能混凝土的原料包括：复胶液芯纤维40份～60份；硅酸盐水泥950份～1000份；稻壳灰160份～170份；铝钒土900份～1200份；璃粉70份～90份；聚丙烯纤维50份～70份；水145份～170份；羧酸减水剂40份～60份。通过添加了短而细的修复胶液芯纤维，当混凝土结构产生裂缝时渗出液体修补裂缝可以防止钢筋腐蚀和氧化，并能在损坏时“再生”，具有超高强度、高韧性、高耐久性和高体积稳定性等特点。
