Anti-corrosion of embedded anchor bolts

After checking, there are no relevant regulatory requirements. In the previous construction projects, the anchor bolts were not required to be anti-corrosion. They were only required to apply butter. It seems that the owner has a problem, because it can be imagined that if only the upper part of the anchor bolts is anti-corrosion, which parts are all anti-corrosion? What's more, the parts exposed to the air need to be smeared with butter. The anti-corrosion effect is definitely no worse than paint? Therefore, it should not be antiseptic. However, if the owner requires anti-corrosion, and the drawings do not require it, a visa can be applied for.

The underground part depends on the quality of the groundwater. If it is alkaline, brush it with cold base oil. The above-ground part can be smeared with butter.

You cannot say that the owner has a problem just because the anchor bolts are required to be anti-corrosion. Butter only has some effect on anti-rust. We are a service unit and can meet customer requirements without affecting the quality of the project. I have done it and found no adverse effects. Just throw the anchor bolts with sandpaper, and then apply a thin layer of asphalt paint (if the viscosity is high, you can mix it with some rosin water). It will not affect the thread fit, and it can play an anti-corrosion role. Of course, you can also judge the use of anti-corrosion materials based on the degree of corrosion on site. The lower part of the thread is better treated. I hope it can help you.
