PROBLEM TO BE SOLVED: To provide a concrete product configured to reliably read out information from an IC tag, to facilitate detecting a position of the IC tag, and to surely secure concrete strength.SOLUTION: In a concrete segment 10, an IC tag is built into any one of two or more spacers 20 connected with a reinforcement basket 11 when manufacturing the concrete segment 10. The spacers 20 are connected with reinforcement by a reinforcement holding fitting 22. Because the spacers 20 appear in an inner circumferential surface, a position of the IC tag can be easily detected. The spacers 20 embed the IC tag by an alkaline material or a ceramic material of mortar and ceramic or the like. |
