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

Features

• Wireless technology
• Compact design
• Simultaneous measurement of electrical resistance and temperature
• Optimized frequency for fresh concrete
• Long battery life on a single charge(about 3 months*)
• Mobile application for Android smartphone and tablet
• Easy data sharing
• Patent pending

Standardization

This method of resistivity measurement is not standardized and is suitable for various research applications. However, AASHTO TP 95-11 provides the test standard for surface electrical resistivity measurement. An ASTM standard is also under development for this test.
