Abstract

Besides visual inspections, taking cores or samples and measurements at the concrete surface, the use of embedded sensors can be an effective tool for the assessment of the condition of concrete structures. For new structures sensors can be placed in positions without the possibility of access during use and for existing structures sensors can be used to follow the condition of the structure at relevant selected points. Actually different types of sensor systems are available based on different electrochemical or other methods.
