There are several guidelines that can be followed to prevent steel rebars from rusting during construction. These guidelines include:
1. Proper storage: Steel rebars should be stored in a dry and covered area in order to protect them from moisture. It is important to keep them off the ground and away from any sources of water, such as puddles or wet concrete.
2. Surface preparation: Before installing the rebars, it is necessary to inspect them for any signs of rust or corrosion. If any are found, they should be cleaned using a wire brush or sandblasting to remove the rust and create a clean surface for proper adhesion.
3. Coating: Applying a protective coating to the rebars can help prevent rusting. This can be done using epoxy, zinc, or other anti-corrosion coatings. It is important to apply the coating evenly and according to the manufacturer's instructions.
4. Proper spacing: When placing rebars in concrete, it is crucial to ensure that they are spaced adequately to allow for proper ventilation and to prevent moisture from being trapped between them. The spacing should be in accordance with the design specifications or as recommended by structural engineers.
5. Adequate concrete cover: The rebars should have a sufficient concrete cover to protect them from moisture and corrosion. The thickness of this cover should meet the design requirements and should be maintained throughout the construction process.
6. Proper curing: After the rebars are installed, it is important to properly cure the concrete to ensure it reaches its maximum strength and durability. Proper curing methods, such as using curing compounds or covering the concrete with plastic sheeting, can help prevent moisture penetration and rusting of the rebars.
7. Regular inspections: Regular inspections of the rebars should be conducted during construction to identify any signs of rust or corrosion. If any are found, appropriate measures should be taken to address the issue promptly and prevent further damage.
By following these guidelines, construction professionals can minimize the risk of steel rebars rusting during construction, thus ensuring the structural integrity and longevity of the project.

There are several guidelines to prevent steel rebars from rusting during construction. Firstly, rebars should be stored in a dry area to avoid moisture exposure. Secondly, they should be covered with a waterproof material to protect them from rain or snow. Thirdly, rebars should not be in direct contact with the ground to prevent moisture absorption. Additionally, using epoxy coating or galvanization can provide an extra layer of protection against rust. Lastly, proper curing of concrete should be ensured to minimize the risk of moisture penetration into the rebars.
