intelliRock III Maturity Logger

Real-Time Concrete Strength Logger

intelliRock Maturity Loggers analyze the time and temperature profile of in–place concrete to calculate its strength in real–time with the push of a button. The maturity loggers are based on ASTM C 1074 "Standard Practice for Estimating Concrete Strength by the Maturity Method."

Document Early Strength and Temperature Information
Speed up concrete operations and extend the construction calendar in cooler weather
Improve quality control with early validation of batching consistency while decreasing labor and material costs
The logger stores the current maturity and temperature value every minute for 180 days
