Anti-corrosion spraying ultra-high performance concrete, anti-corrosion coating and construction method thereof
The invention discloses anti-corrosion jet ultra-high performance concrete, an anti-corrosion coating and a construction method thereof, and the anti-corrosion jet ultra-high performance concrete is composed of 800-900 parts by mass of cement, 100-200 parts by mass of silica fume, 20-80 parts by mass of metakaolin, 400-500 parts by mass of quartz sand of 40-80 meshes, 600-700 parts by mass of quartz sand of 20-40 meshes, 4-6 parts by mass of a water reducing agent, 4-8 parts by mass of a rheology modifier, 100-150 parts by mass of steel fibers and 190-200 parts by mass of water. The rheology modifier is composed of a thixotropic agent, a thickening agent and a denaturing agent, and the mass ratio of the thixotropic agent to the thickening agent to the denaturing agent is 5: 2: 2. The problem that an anticorrosive coating of a sewage facility concrete structure of an existing municipal sewage treatment plant is prone to being damaged, and consequently the concrete structure is corroded is solved.
本发明公开了一种防腐喷射超高性能混凝土、防腐镀层及其施工方法，由800～900质量份的水泥、100～200质量份的硅灰、20～80质量份的偏高岭土、400～500质量份的40～80目石英砂、600～700质量份的20～40目石英砂、4～6质量份的减水剂、4～8质量份的流变改性剂，100～150质量份的钢纤维和190～200质量份的水组成，所述流变改性剂由触变剂、增稠剂、变性剂组成，所述触变剂与所述增稠剂、所述变性剂的质量比为5:2:2。本发明解决了现有的市政污水处理厂的污水设施混凝土构筑物的防腐涂层易被破坏导致混凝土构筑物被腐蚀的问题。
