Pulse compression technique applied to ultrasonic nondestructive testing of concrete
The pulse compression technique is successfully and widely used in many fields for improving the signal to noise ratio (SNR); which is especially useful when the environment is noisy and the SNR is poor. Since high frequency ultrasound is strongly attenuated in concrete, only low frequency ultrasound can be used in ultrasonic nondestructive testing (NDT) of concrete. In this study the pulse com...

15 صفحه اولUltrasonic Nondestructive Testing Method for Evaluation of Annular Seals
Drilling boreholes is common practice in geotechnical and geoenvironmental investigations and in various other ex ploration, testing, and monitoring appli cations. When a casing is placed in a borehole an annular space is created be tween the casing and the surrounding soil. If not properly sealed, this annular space can be a potential path for trans port of contaminants in the subsurface e...
