Which risk increases when seawater permeates concrete rebar supports?

💡 Explanation

Galvanic corrosion accelerates because chloride ions increase the electrolyte conductivity between dissimilar metals present in the reinforcing steel. This causes rapid oxidation of the less noble metal, therefore corrosion risk increases rather than other effects on the concrete tensile load.
