Characterization of ultrasonic properties of concrete
Comparisons between the numerical and experimental results show that the theoretical model captures some essential characteristics of ultrasonic waves in concrete. The effects of size, mechanical properties, and bonding condition at the interfaces of aggregates on the wave dispersion and attenuation are investigated.
Rubblizing to rehabilitate existing pavements
Rubblization is the process of fracturing the worn-out concrete into small, typically 2- to 6-inch, pieces and converting it into an interlocked but flexible base material. The rubblizing process breaks the bonds between any reinforcing steel and the concrete, eliminates slab movement, and nearly eliminates the possibility of reflective cracking.
ULTRASONIC TESTING OF CONCRETE

What is Ultrasonic Testing of Concrete for Compressive Strength?
theconstructorDoes ultrasonic pulse velocity affect crushing strength of concrete?Higher the elastic modulus, density and integrity of the concrete, higher is the pulse velocity. The ultrasonic pulse velocity depends on the density and elastic properties of the material being tested. Though pulse velocity is related with crushing strength of concrete, yet no statistical correlation can be applied.What is Ultrasonic Testing of Concrete for Compressive Strength?
theconstructorHow effective is non-linear ultrasonic testing in concrete damage detection?It was shown that non-linear ultrasonic testing method, based on higher order harmonic generation, is highly effective in damage detection in concrete. The second and third harmonic ratios have shown to be very sensitive to compression induced damage in concrete. Their sensitivity increased as w/c increased.Non-linear ultrasonic evaluation of damaged concrete based
sciencedirectHow does ultrasonic pulse travel through concrete?When ultrasonic pulse travelling through concrete meets a concrete-air interface, there is a negligible transmission of energy across this interface so that any air filled crack or void lying directly between the transducers will obstruct the direct beam of ultrasonic when the void has a projected area larger than the area of transducer faces.What is Ultrasonic Testing of Concrete for Compressive Strength?
