Advanced NDT Methods for Civil Engineering
Advanced NDT Methods for Civil Engineering: Potentials / Limitations / Typical Applications
1. GENERAL
• Non-destructive testing for civil engineering: classification by measuring principle and application
• Direct testing and non-destructive testing: integration and complementarity
2. STRUCUTRAL DETAILS ASSESSMENT
• Rebar location with traditional covermeters
• 3D Imaging with Ground Penetrating Radar and Shear Wave Ultrasonic Tomography
• Complementary techniques (thermography and borehole inspection)
3 EVALUATION OF CONCRETE COMPRESSIVE STRENGTH
• Core drilling and direct compression testing
• Rebound hammer testing
• Ultrasonic pulse velocity and Sonreb method
• Complementary techniques (extraction test and penetration test)
• Calibration curves between compressive strength and NDT parameters
4. EVALUATION OF DEFECTS AND WEATHERING OF REINFORCED CONCRETE
• Durability and corrosion analysis with half-cell potential and electrical resistivity methodologies
• Cracks, voids, grouting defects with traditional Ultrasonic Pulse Velocity measurement and Shear Wave Ultrasonic Tomography
