Feasibility study on the traceability system of concrete production

点击翻译按钮获取中文摘要

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 concrete and the IC reader/writer (R/W) outside the concrete. The communication performance of IC tag embedded into the concrete was examined in this study.
