WIRELESS CONCRETE RESISTIVITY : Giatec SmartBox™ is a compact wireless device for the measurement and monitoring
of electrical resistance and temperature in fresh concrete. The continuous measurements are recorded on SmartBox™ and can be downloaded using the mobile application on Android smartphone/tablet.
The electrical resistivity of fresh concrete has been shown to provide a good indication on the water content as well as setting and hardening of concrete. SmartBox™ provides an efficient tool for various research studies in these areas.
APPLICATIONS : The SmartBox™ concrete testing equipment can be used to monitor the electrical resistivity and temperature of fresh concrete. This can provide information on:
- Water content in fresh concrete
- Prediction of setting
- Setting time measurement
- Crack detection in concrete
