Which risk increases when concrete permeability rises when exposed rebar is subject to chloride ingress?

💡 Explanation

When concrete permeability rises, chloride ingress reaches the rebar because the porous structure allows easy diffusion, breaking down the passive layer and starting the corrosionprocess. Therefore, increased corrosion rates take hold, rather than diminished strength, increased expansion, or reduced resistance that involves concrete matrix degradation rather than the rebar's stability.
