Baotou GRC The components are mainly connected and fixed by the embedded reinforcement and the steel frame or embedded parts on the main structure. If GRC The component cracks due to the decoration of embedded reinforcement, which will lead to component fracture and potential safety hazard. Therefore, the reinforcement shall be strictly controlled not to rust. So how to improve the rust prevention ability of rebar?
1. Use of reinforcement: use of corrosion resistant reinforcement, galvanized reinforcement and epoxy coated reinforcement in concrete can effectively isolate harmful ions penetrating into concrete and contact corrosion of reinforcement.
2. Rebar antirust agent: add rebar antirust agent into the concrete to prevent harmful ions from corroding the rebar or slow down the corrosion rate.
3. Improve the protection capacity of concrete itself: excellent materials shall be selected during construction, and material quality, water cement ratio and cement consumption shall be strictly controlled to ensure the compactness of concrete. If necessary, the thickness of the protective layer can be properly increased, and the use of chlorine salt is prohibited.
4. The isolation layer shall be coated outside the construction: it can improve the waterproof and durability of concrete. Isolating the corrosive environment can delay the carbonization speed and protect the concrete. During construction, the attachments on the concrete surface shall be clear, and shall be fully dried after being washed with water. Apply mortar or insulating layer on the construction surface. Such as asphalt coating and epoxy resin coating.
