Role of Sensors in Corrosion Monitoring and Durability Assessment in concrete Structures: the State of the Art

Many extensive studies in the area of sensor technology for corrosion monitoring in concrete structures have increasingly been carried out in recent years. In this paper, the principles and use of various sensors involved in the health monitoring of concrete structures are described. Special attention was given to the review of various sensing devices, the selection of reliable sensing devices for detecting reinforcement corrosion in particular environments and the efficiency of the devices used. Various sensing operations in new and existing concrete structures for corrosion risk, humidity, temperature, strain and stress are also described.
