Disclosed is a method for detecting flooding, freshets, or inundation in a structure. The aforementioned structure is characterized by an arrangement wherein one or more active type RFIDs are buried or installed in those places of the structure where flooding, freshets, or inundation is to be detected; wherein a receiving means which receives electromagnetic waves transmitted by one or more active type RFIDs in the structure is provided in or near the structure; and wherein if flooding, freshets, or inundation occurs in the structure, with the result that water intrudes into one or more areas between those locations in the structure where one or more active type RFIDs are buried or installed and the location where the aforementioned receiving means is provided, then the receiving means receives electromagnetic waves which are transmitted by the aforementioned active type RFID or RFIDs and the intensity of which is changed by the aforementioned water, thereby detecting flooding, freshets, or inundation in the structure. Provided are a method for detecting water in the aforementioned structure and a device for detecting water in those structural members and that structure to which is applied the aforementioned method for detecting water in the structure.
A control method of ready-mixed concrete for controlling the quality and shipment of ready-mixed concrete delivered by a ready-mixed concrete truck, comprising the step of attaching a non-contact communication medium able to be written/read to/from the outside to the ready-mixed concrete truck, the step of writing the identification information of the ready-mixed concrete truck to the non-contact communication medium, the step of writing at a ready-mixed concrete shipper the quality of the ready-mixed concrete to be loaded in the ready-mixed concrete truck and shipping quality/shipping information to the non-contact communication medium, and the step of reading at a ready-mixed concrete delivery destination the quality/shipping information from the non-contact communication medium.

CONCRETE STRUCTURE, METHOD FOR MANUFACTURING THE CONCRETE STRUCTURE, AND METHOD FOR MANAGING THE STRUCTURE AND METHOD
This invention provides a concrete product, a method for manufacturing the product, and a method for managing the product and method, which can manage various data on a concrete product per se and history in a manufacturing process regarding casting of concrete in a simple, accurate, and reliable manner and thus can realize easy utilization of the data, for example, in inventory and delivery management, can realize follow-up check later, and can realize utilization in tracerability. In an L-type retaining wall as such a concrete product, a thin plate-shaped IC tag (3)is embedded near a concrete body (1) cast face so that an antenna part (13) on its antenna face is parallel to the concrete body (1) on its side face (1a).
