TOPPAN Holdings Co., Ltd.
Developed an “RFID sensor system” to DX the strength development management of TOPPAN edge concrete with Haseko Corporation
Promoting improved work efficiency and reduced environmental impact at construction sites
……
TOPPAN Edge Co., Ltd. (Head office: Minato-ku, Tokyo, President and CEO: Soeda) is a group company of Haseko Corporation (Head office: Minato-ku, Tokyo, President and CEO: Kazuo Ikegami, hereinafter referred to as Haseko Corporation) and TOPPAN Holdings. Hideki (hereinafter referred to as TOPPAN Edge) has been conducting joint research since April 2020 to advance DX (digital transformation) at construction sites. As a result of this joint research, we have developed an “RFID sensor system” (patent pending, hereinafter referred to as “RFID sensor system”) that uses RFID (*1) and temperature sensing technology to remotely check the strength development of concrete as it hardens. ) was developed.
Concrete poured into formwork at a construction site moves to the next process, such as removing the formwork, depending on the strength of the concrete in the early stage of hardening. Conventionally, the strength of concrete in the early stage of hardening is confirmed by compressive strength tests conducted by external institutions using specimens. This system estimates the strength of concrete in the early stage of hardening based on the temperature of concrete measured by an RFID sensor installed inside the formwork into which concrete is poured, and enables the development of concrete strength to be monitored remotely in real time. This eliminates the need for compressive strength testing by an external organization, and can be expected to improve work efficiency by quickly moving on to the next construction process, and reduce CO2 emissions and waste by reducing the number of specimens.
In addition, verification of this system has been carried out since early 2024 at construction sites being advanced by Haseko Corporation, and we are working to establish an operational method for construction management using this system and improve operability and work efficiency. We aim for full-scale introduction in fiscal 2025.

Overview of “RFID sensor (sticker type)”
■ Features of this system
・Improving work efficiency using RFID
This system measures and records the temperature data of poured concrete by installing an “RFID sensor” inside the formwork into which concrete is poured and a “reader” on the outside. Since the “RFID sensor” is in the form of a sticker, it can be installed by simply pasting it on the inside of the formwork, and there is no need for wiring or processing of the formwork during installation. In addition, the RFID sensor is extremely thin and leaves only a few traces on the concrete surface after the formwork is removed, so there is no need to consider rework or finishing work.
・Concrete strength development can be confirmed remotely using wireless communication
The data measured by the “RFID sensor” is recorded wirelessly with a reader installed outside the formwork. Recorded temperature data is automatically transferred to the cloud. By using this temperature data to estimate the strength of concrete from the estimation formula specified in the Building Standards Act, it is possible to check the strength development from a remote location in real time.

■ Future developments
Haseko Corporation and TOPPAN Edge will continue to jointly promote the development and popularization of DX at construction sites, with the aim of reducing environmental impact through work style reform, CO2 emissions, and waste reduction.
*1 RFID (Radio Frequency Identification) is an automatic recognition technology that uses wireless communication such as electromagnetic fields and radio waves to read and write information on IC tags and other devices without contact. RFID tags with temperature sensors have a built-in temperature sensor in addition to a unique ID. In addition, since it operates using radio waves emitted from the reader/writer as a power source, there is no need to replace batteries, and the sensor can be made smaller and thinner.
