Structure-enhanced and corrosion-resistant reinforced concrete member and preparation method thereof
The invention discloses a structure-enhanced and corrosion-resistant reinforced concrete member and a preparation method thereof, the reinforced concrete member comprises a member body and a zinc alloy plate fixedly connected with the member body, and the zinc alloy plate is at least partially exposed out of the concrete body to form sacrificial anode protection for the member body. The component body comprises a reinforcement cage, the surface of a reinforcement is coated with epoxy zinc-rich primer, and a cathode can be protected. The embedded part embedded into the concrete can be formed on the zinc alloy plate, and the embedded part and the component body are solidified into a whole after the concrete is poured and solidified, so that the overall strength of the reinforced concrete component can be improved. Nano montmorillonite/poly (N-isopropylacrylamide) is adopted as a chloride ion resistant additive in the concrete, the concrete has a cross-linked network structure, crack tip stress can be effectively dispersed, the crack resistance of the reinforced concrete is improved, the chloride ion erosion resistance of the concrete is enhanced, and a reinforced concrete member has good mechanical properties and corrosion resistance and is suitable for being used in the field of concrete construction. The service life and the use stability are obviously prolonged.
本发明公开了一种结构增强与耐腐蚀钢筋混凝土构件及其制备方法，钢筋混凝土构件包括构件本体以及与构件本体固定连接的锌合金板材，锌合金板材至少部分外露于混凝土本体，以对所述构件本体形成牺牲阳极保护。构件本体包括钢筋笼，钢筋表面涂覆有环氧富锌底漆，可保护阴极。锌合金板材上可形成嵌入混凝土内的嵌入部，在混凝土浇筑固化后与构件本体固化成一体，可提高钢筋混凝土构件的整体强度。混凝土中采用纳米蒙脱石/聚N‑异丙基丙烯酰胺为抗氯离子添加剂，具有交联网状结构，能够有效分散裂纹尖端应力，提高钢筋混凝土抗裂性，加强混凝土的抗氯离子侵蚀性，本发明的钢筋混凝土构件具有较好的力学性能和耐腐蚀性，使用寿命和使用稳定性显著延长。
