Damage detection in concrete structures using smart piezoelectric sensors as concrete’s aggregates

Abstract

The present PhD thesis deals with the application of piezoelectric materials in non-destructive testing of concrete, and in particular, with their applicability in damage detection of structural elements. Moreover, the application of piezoelectric materials in monitoring of early age concrete mechanical behavior is investigated. Due to the need for continuous gathering of information regarding the condition of concrete structural members from the first stages of their construction, one of the main aims of the present research is the design and development of monitoring devices based on piezoelectric materials, which are embedded to concrete mass and characterized as “smart” piezoelectric aggregates.The main technique that has been employed to monitor the structural integrity of the concrete is the method of Electro-Mechanical Impedance. This method is based on a comparative analysis between a reference response spectrum which corresponds to the state of the “healthy” (without damages) ...
