Zinc on Concrete

[jenofstructures]

from the title itself, i would like to ask if Zinc is bad for concrete?

While searching on this matter, ive seen a link where they telling that a zinc can crack a concrete, because of corrosion while another website is telling that a zinc is sprayed on a certain part of a bridge to metalized it

Please educate me on this matter

Zinc, when applied to the exterior of concrete in a metalizing process, is used as part of a cathodic protection system for the rebar and to inhibit chloride intrusion in concrete. It's OK when applied in this manner.

Zinc can crack concrete when embedded in it because of its oxide expansion during the corrosion process. It doesn't always happen, but it can. It is usually a result of partially embedding galvanized steel parts in concrete.

thank you very much

but how about if the zinc itself, together with concrete mixture became a part of infill to the masonry?

That doesn't help. It has a very limited dissipation capability. If you want to do that, use lithium or sodium nitrite.
