Abstract

RFID technology is useful for developing a rational building information traceability system. IC-tag is an important vehicle of RFID technology. Several methods of installing IC-tags on building materials and components exist. One method is to install an IC-tag inside concrete material without a screw and an adhesive. This paper describes a study on the communication performance of several types of IC-tags installed inside concrete. Communication frequency of IC-tags and readers used in the experiment were 13.56MHz, 2.45GHz and UHF band. In addition, the influence of a reinforcing bar in the concrete on communication performance of IC-tag was studied.
