A new system for measuring, analyzing and reporting temperatures generated by mass concrete pours has reached the market. The TEMP (Thermal Evaluation of Mass Pours) system makes it simple and cost efficient to meet requirements of thermal control plans and monitor concrete maturity. TEMP measures concrete temperatures during curing in various locations of the pour using patented Thermal Wire cables, which feature custom-spaced digital temperature sensors. The cables are cast into the concrete, often tied to the reinforcement. The TEMP system is unique in making it possible to have multiple measuring points in a single Thermal Wire cable, allowing the design of each monitoring project with as few or as many temperature sensors per cable as required to minimize cost.
- A single external TEMP data logger collects and stores temperature measurements of all sensors of the Thermal Wire cable.
- No batteries in the sensors themselves, only in the external TEMP data logger and lasts 28 days, is rechargeable and is easily replaceable when low, making it possible to monitor and store temperature data indefinitely.
- Data is transferred from the data loggers to the TEMP main unit for quick observation whenever desired – the main unit has a high resolution screen visible in all lighting conditions.
- Analysis and reporting is performed with the TEMP-S software, which makes it fast and intuitive to generate a customized presentation-quality report. It displays measured temperatures versus time in graphical and tabular forms, maximum and minimum temperatures, and the maximum temperature differentials (∆T), along with allowable limits entered by the user.
- TEMP-S calculates concrete maturity based on measured temperatures, and helps the user estimate concrete strength based on a user-determined strength-maturity relationship.
- Allows users to comply with maturity monitoring requirements of ASTM C1074 – 11 Standard Practice for Estimating Concrete Strength by the Maturity Method.
