Smart Rock2, Wireless Maturity Sensor

SmartRock2 is a rugged, mobile app-based wireless sensor for monitoring the temperature of concrete from fresh to hardened stage. It also estimates concrete strength, based on the maturity concept. The SmartRock2 can be placed in the concrete formwork, no more than 3" deep (installed on the rebar) before pouring, to monitor the temperature of concrete in situ. The continuous measurements are recorded on the SmartRock2 memory and can be downloaded at any time during the concrete setting and hardening onsite using the mobile application on a smartphone or tablet device.

The continuous monitoring of concrete temperature can be used as a QC/QA method as well as maturity-based strength estimation of concrete. The field monitoring of concrete temperature can also help with optimizing the formwork removal time, application of load on the structure, and adjusting the curing temperature of concrete onsite.
SmartRock2 can be used to monitor the temperature of fresh and hardened concrete. This information can be used for:

  • Available in 16" and 10 ft. cable lengths
  • Optimization of curing conditions
  • Quality control in the field
  • Estimation of strength (ASTM C1074)
  • Formwork removal timing
  • Post-tensioning
  • Opening road to traffic
  • Monitoring temperature gradients in mass concrete

Features (Hardware)

  • Wireless technology
  • Rugged and waterproof design
  • Easy installation and activation by tying the wires together
  • Extended temperature sensor cable for mass concrete
  • Long battery life (up to 3-4 months after installation)
  • Patents pending

Features (Software)

  • Real-time data display (e.g. temperature, strength, max-min)
  • Maturity calibration database
  • Free Android and iOS apps for smartphone and tablet
  • Easy data sharing between devices
  • Project management tools
  • PDF report generation
  • Photos and blueprints attachment
  • Goal limit setting for temperature and strength
