Non-Destructive Corrosion Inspection of Reinforced Concrete Using Ground-Penetrating Radar: A Review
Reduced maintenance costs of concrete structures can be ensured by efficient and comprehensive condition assessment. Ground-penetrating radar (GPR) has been widely used in the condition assessment of reinforced concrete structures and it provides completely non-destructive results in real-time. It i...
