Does pouring concrete over rusted rebar stop the rust?
Yes — sound concrete is alkaline enough to passivate steel and halt corrosion. Light surface rust is fine and helps bond. Loose scale and section loss are not.
2What is reinforced concrete?
Concrete is strong in compression and weak in tension, so steel carries the tension. Rebar grades, welded wire, fibers, post-tensioning, cover and corrosion.
