title = "Application of non-linear mechanical wave behavior to characterize cement based materials",
abstract = "Non-linear wave propagation and vibration methods have been applied to detect and characterize very small scale damage and porosity in engineering materials. In recent years, several investigators have attempted to extend this promising method to characterize concrete and other cement-based materials. In this paper, the basis of non-linear tests is described and previous efforts on cement based materials are summarized. The authors' efforts on this topic are then presented. A practical nonlinear vibration testing method is described, and preliminary results from cement-based materials containing mechanical and physical-chemical induced damage types are shown. The obtained non-linear characteristics illustrate the promise of the method for sensitive detection of internal damage in cement-based materials.",
