What are the main differences between Destructive and Non-Destructive Tests (NDT)?

Destructive Tests (DT): Require breaking or cutting the concrete sample (e.g., Compressive Strength Test, Flexural Strength Test). Non-Destructive Tests (NDT): Assess concrete properties without damaging the structure (e.g., Rebound Hammer, UPV, RCPT).

What are the main non-destructive tests (NDT) for concrete quality assessment?

NDT methods evaluate concrete without damaging the structure: Rebound Hammer Test: Measures surface hardness and estimated strength. Ultrasonic Pulse Velocity (UPV): Detects internal cracks and uniformity. Rapid Chloride Penetration Test (RCPT): Assesses chloride permeability and corrosion risk. Half-Cell Potential Test: Determines corrosion activity in reinforced concrete. Carbonation Test: Identifies carbonation depth and risk of steel corrosion. Infrared Thermography: Detects hidden defects using thermal imaging.
