Abstract
The reinforcement corrosion has a serious impact on durability and safety of reinforced concrete structures. Based on radio frequency technology, the wireless sensor for the monitoring of reinforcement corrosion is investigated in this paper. The sensors are fabricated and experiments on the sensors are carried out. Experimental results show that it is feasible to determine whether the steel wire is broken or not by monitoring the resonant frequency of the circuit, and the sensor with spring switch designed in this paper can solve the problem of the resonant frequency missing of the sensor during the process of the steel wire corrosion. The encapsulation materials for the sensors are studied.
