A Comprehensive Review on Wave-Based NDT Techniques for Evaluation of Concrete Structure

摘要

This paper presents several wave based NdT methods for testing concrete structures. The methods include ultrasonic pulse velocity, impact-echo, spectral analysis of surface waves (SASW), skimming longitudinal and Rayleigh wave (SLRW), Inversion of diffracted wave and the Ground penetrating radar methods. The basic principles and their associated applications of these method are described.
