内容简介：

Versatile piezoceramic-based transducers have proven to be employed as both active and passive sensors in structural health monitoring. However, most of the piezoceramic patches are fragile and can be easily damaged in practical applications. A smart aggregate is designed as a sandwiched structure to protect the fragile piezoceramic patch with two marble or concrete blocks. The developed smart aggregate transducer can significantly provide the environmental resistance and improve service life of piezoceramic patches in structural health monitoring. Recently, smart aggregates have been successfully deployed to monitor various types of damage in civil structures, including crack in concrete beams or piles, bond slip damage in steel plated structures, water migration detection in concrete, early age concrete hydration monitoring, etc. We believe that, in the future, smart aggregate-based structural health monitoring can help engineers to ensure the structural safety and functionality.
