Communication performance of IC-tags installed inside large-size concrete specimens

It is important to develop an information traceability system on the process of concrete production. One method is to record the information about the concrete production with IC-tags, and to install them inside the concrete. This method has a characteristic to keep the information inside the concrete itself. On the other hand, this method requires communication performance between IC-tags inside the concrete and the reader outside the concrete. The communication performance of IC-tags installed inside the small-size specimens was clarified in our previous study. This paper describes a study on the communication performance of several types of IC-tags installed inside the large-size concrete specimens.
