Novel Method to determine moisture content in concrete using Ultrasound propagation NDE under a simulated precipitation

摘要

24 concrete cubes were investigated during 24 hours under a constant simulated precipitation in order to measure the wave propagation effect using different values of water cement ratio, vibrated time or even cured types. A moisture content profile was measured at the top surface. It was found that the cured type had an important impact on the wave propagation, and also vibrated time.
