  1. Ultrasonic Pulse Velocity • British BS 1881, Testing Concrete Pt 203 • USA ASTM C597 (less comprehensive)

  2. Crack Depth C = b* Example with TICO For inclined cracks Shape of time t b b

  3. Influence by Temperature Air dry concrete Saturated concrete Higher temperature, higher sound velocity between 0 and 30 Grad C only about +/- 1 % Below zero high influence
