抄録

Technical feasibility to mix-in IC tags into ready-mixed concrete is discussed, focusing on RF communication performance under flowing conditions. Firstly, flowing conditions (i.e. flow speed, concrete thickness) at agitating truck chute and pumping pipe is summarized based on on-site measurement and standard specifications. Secondary, experimental method and RF communication performance index for RF communication is proposed. It has been estimated that 20-40% of IC tags could be found and captured, while non are data read-writable. On-site experiment result was highly consistent with the experimental estimation.
