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.
