Implication

Experimental study investigates shear performance of corroded concrete beams, suggesting effective repair strategies.

Key Points

This work aims to evaluate the shear performance of naturally corroded prestressed concrete beams and the effectiveness of repair interventions.
Conducted visual inspections to identify surface corrosion damage.
Performed electrochemical measurements to assess corrosion state and map degradation.
Evaluated shear capacity using three-point bending tests and analyzed strands with laser scanner techniques.
The study reveals significant dependency of shear capacity on the effectiveness of patch-repairing interventions.
Advanced diagnostic techniques were essential for reliable assessment and correlation of damage data.
Corrosion morphology mapping indicated specific patterns of degradation across the beam length.
