Ok all, this question has been bugging me....
In coastal environments, condo's that are of steel reinforced design have occasional issues with rebar rot. The rebar rusts deep inside the concrete, usually on the balconies and at the balcony to building joints. In severe cases the concrete around the rusting bar "pops" and flakes off.
So.....if we have a gunnite pool filled with salt water, what kind of migration to the rebar can we expect? Will the surface walls of the pool spall?
Has this been discussed before?
