← TechnologyWhich outcome is LEAST likely following the complete oxidative degradation of epoxy coating reinforcing a pre-stressed concrete beam near a marine environment?
A)Increased chloride ion ingress rate
B)Loss of prestress over time
C)Increased beam tensile strength✓
D)Accelerated rebar corrosion rate
💡 Explanation
Oxidative epoxy degradation permits chloride ions to reach the rebar, promoting corrosion; this reduces the cross-sectional area of steel supporting tensile loads via weakened steel binding because oxygen penetration weakens adhesion of epoxy to the concrete, therefore decreasing net tensile capability, rather than increasing it.
