Concrete embedded sacrificial anode structure and protective shell and preparation method thereof
The invention discloses a concrete embedded sacrificial anode structure and a protective shell and a preparation method thereof, and belongs to the technical field of reinforcement protection in concrete structures. The concrete embedded sacrificial anode protection shell comprises double-layer composite mortar, the water absorption rate of the shell mortar layer is not lower than 30%, the strength of the shell mortar layer is not lower than 25 MPa, the water absorption rate of the lining mortar layer is not lower than 90%, and the strength of the lining mortar layer is not higher than 5 MPa. The protective shell can effectively solve the problem that in the prior art, when a sacrificial anode method is adopted for protecting steel bars in a concrete structure, volume expansion generated by corrosion of anode metal is prone to damaging a concrete entity, meanwhile, the working environments such as humidity and pH value of the anode metal can be guaranteed, and the service life of the anode metal is prolonged. And the anti-corrosion effect of the steel bar is further ensured.
本发明公开了一种混凝土埋入式牺牲阳极结构及其保护外壳和制备方法，属于混凝土结构中钢筋保护技术领域。本发明的一种混凝土埋入式牺牲阳极保护外壳，该保护外壳包括双层复合砂浆，其中外壳砂浆层的吸水率不低于30％，强度不小于25MPa，内衬砂浆层的吸水率不低于90％，强度不大于5Mpa。采用本发明的保护外壳可以有效解决现有技术中采用牺牲阳极法对混凝土结构中钢筋进行防护时，阳极金属锈蚀产生的体积膨胀易对混凝土实体造成破坏的问题，同时还可以保证阳极金属工作的湿度、酸碱度等环境，进而保证钢筋防锈蚀效果。
