(Concrete Filling Detector)


The “Jutender” is a completely new high precision concrete filling detection system developed using Akebono’s vibration analysis technology.

The system includes a small vibration device and a detection component. The later sends a signal that displays a red (air), green (concrete) or yellow (defective/water) image on an LCD screen that allows the viewer to determine if there’s still empty space to be filled. The data results are then transferred for storage and analysis to a personal computer, which gives ability to control the finishing time data etc.


  1. No need for calibration of the device. It is possible to detect the faulty state of a concrete filling (both due to air and water gaps) with only one vibration device and without having to adjust the settings.*
  2. The small vibration device can be used in a variety of spaces, even in very narrow and thin ones.
  3. The user interface is easy to understand. The color codes display clearly the status of the filling in real time and the data (e.g. finishing time) can be saved and stored for future analysis.
  • * This system is not intended to guarantee the quality of the concrete structure, such as detecting the status of the entire concrete filling. It is instead intended to detect the status of the filling around the area where the vibration device is installed. Additionally the device has to be mounted at an appropriate place to give accurate readings.

Application examples

  • Use in situations where visual confirmation of the concrete filling status is difficult
  • At constructions with high density of reinforcing bars etc. the device can confirm if there are any rock pockets etc
  • Confirm the state of the concrete flow and fluidity (measuring the time it takes to fill the mold with concrete)
  • Confirm if the CFT (Concrete Filled Steel Tube) diaphragm’s under side has been filled
  • Confirm of the concrete filling status of tunnel roof
