Abstract

 It is important to develop an information traceability system on the process of concrete production. One method is to record an identification number or the information about the concrete production with wireless IC tag, and to put it into the concrete that has not yet hardened. This method has a characteristic to keep the information inside the concrete itself. On the other hand, this method requires communication performance between IC tag inside the reinforced concrete member and the IC reader/writer outside the concrete member. This paper investigates the communication performance of IC tag embedded in the actual reinforced concrete floor slab.<br> Firstly, we have developed a new communication performance index to evaluate the possibility of wireless communication of the IC tags embedded inside concrete slabs. The index has been calculated through the experiments on various molding conditions such as relative locations of reader/writer and reinforcing bars (6 standards), relative direction of IC tags against reader/writer (24 standards), and various depth from concrete surface.<br> Secondary, the index is measured and calculated in actual slab concreting works, in order to investigate the applicability of the index. The calculated index values were larger than the measured values, although only one construction site is available for this comparison.<br> Lastly, the least number of IC tags to make a product traceable has been investigated through the above experimental results and analysis.
