Wave dispersion in fresh and hardened concrete through the prism of gradient elasticity Vrije Universiteit Brussel
The determination of the early age concrete properties and the monitoring of their evolution is the key point for an optimized construction with assured high quality. To this direction, the ultrasonic nondestructive testing technique is highly promising since it gives feedback on the mechanical properties and damage condition, allowing for the continuous interrogation of the material. It has experimentally been observed that concrete at both its ...
