If the metal in the anode and the cathode needs to be replaced because the lye in cement causes it to degrade over time, does the whole cement structure need to be replaced?
It would be so awesome if you could basically make the anode and cathode be the rebar. Then your construction method would be almost identical to a regular building, with some additional wiring.
I don’t know if lye is still active (if that’s the right word) after the concrete sets. And this article says concrete has a high pH that resists corrosion.
