Corrosive agents penetrate steel rebar causing two competing harmful mechanisms: non-uniform corrosion generates excessive volumetric expansion of corrosion products that cracks and spalls concrete cover while gradually reducing cross-section, whereas pitting corrosion
Non-uniform corrosion creates a harmful effect where corrosive agents concentrate at localized points on the steel rebar, forming deep pits that severely reduce the load-bearing cross-section at specific locations while leaving surrounding areas intact, leading to unpre
Current detection methods provide insufficient spatial resolution to identify localized corrosion sites in reinforcing steel bars embedded within concrete, because non-uniform corrosion occurs in discrete zones that don't generate strong signals in area-averaged measure
The fiber-optic sensing element insufficiently detects non-uniform corrosion patterns because localized pitting and crevice corrosion create highly variable spatial damage that the sensing system cannot resolve with adequate precision, resulting in missed detection of c
Dissolved oxygen and corrosive ions in the transported fluid create harmful electrochemical reactions with the copper pipe wall at localized sites where the protective oxide layer provides insufficient isolation, resulting in deep pitting that penetrates the pipe wall r
Non-uniformly expanding corrosion products generate concentrated radial forces at localized points along the reinforcement bar, creating tensile stresses that exceed the concrete cover's constraining capacity, resulting in premature cracking; the goal is to prevent or d
Electrochemical sensors measure corrosion activity in rebar but provide insufficient spatial resolution to detect localized pitting and non-uniform attack patterns, causing underestimation of maximum penetration depth and structural failure risk; the goal is to accurate
Current monitoring sensors inadequately detect non-uniform corrosion in concrete reinforcement due to insufficient spatial resolution and coverage density, causing localized severe corrosion spots (pitting, crack-induced corrosion) to remain undetected while average mea
The corrosion detection sensor insufficiently measures non-uniform damage patterns on structural surfaces, failing to capture spatial variation between localized corrosion zones and general surface degradation, resulting in missed detection of critical corrosion hotspot
Current inspection methods insufficiently measure the three-dimensional non-uniform corrosion depth distribution across reinforcement surfaces in concrete structures, preventing accurate assessment of remaining load-bearing capacity and reliable prediction of structural
