COMMAND Center measures and records internal concrete temperatures as required by specifications for thermal control plans, hot and cold weather concreting, and mass placements.
COMMAND Center temperature sensors automatically collect concrete temperatures at regular intervals during curing. Construction teams use COMMAND Center to ensure concrete temperatures stay within an acceptable range.
COMMAND Center Sensors arrive preconfigured to automatically track and record temperatures. No initialization is required, so construction teams don’t even need to connect to the sensor during placement. Simply secure the sensors in place, pour the concrete over them, and use any compatible COMMAND Center reader to view and analyze the concrete’s temperature history at any time.
When receiving a delivery of fresh concrete, construction teams typically embed a common thermometer into the concrete to measure its temperature. However, a thermometer will not measure and record temperature continuously at regular intervals to identify what the maximum internal concrete temperature is achieved during curing. In addition, a thermometer will not work for monitoring temperature differentials between the core and surface of massive elements as typically required by job specifications and defined by a thermal control plan.
When the internal temperature of a concrete element is in danger of breaching maximum or minimum temperature thresholds, data provided by embedded COMMAND Center Sensors will allow the construction team to take measures to prevent the concrete from exceeding these thresholds.
Benefits of Using COMMAND Center to Monitor Concrete Temperatures
Reduce required site visits
Without COMMAND Center, a contractor might require an employee to visit a project site every two to four hours to collect concrete temperature data in order to comply with a cold weather concreting specification.
Satisfying this cold weather specification is much easier with COMMAND Center. Construction teams can obtain the required temperature data by placing a few COMMAND Center sensors before concrete is poured. Once the concrete is poured, the sensors will automatically begin measuring and storing internal concrete temperatures at any specified time interval.
Closely monitor internal temperatures in challenging conditions
Cold weather concreting can require contractors to implement temperature-controlled curing to prevent hot concrete from experiencing thermal shock after form removal in cold conditions.
By using COMMAND Center Sensors to automatically collect internal temperatures throughout the curing process, contractors can easily monitor in-place concrete for conditions that might lead to thermal shock. COMMAND Center allows contractors to determine exactly if and/or when concrete temperatures have fallen outside specified thresholds. If COMMAND Center indicates that concrete temperatures have breached these thresholds, contractors can apply additional curing as needed so that concrete durability and performance remains uncompromised.
Satisfy mass placement specifications
Mass placement specifications often require the project’s construction team to monitor temperatures at the concrete element’s surface—or other critical location—and center. If the difference in temperatures between the critical location and center is greater than a specified threshold, the contractor may have to remove and replace the element.
COMMAND Center simplifies the process of monitoring temperature differentials. The construction team can place a sensor at each location that needs to be monitored. Once the sensors’ temperature data is imported to the COMMAND Center software, the system will automatically calculate the temperature difference between two sensors. Inspectors can use COMMAND Center to determine whether temperatures within mass elements stay within specifications.
The contractor can use COMMAND Center to quickly identify when this difference comes close to the threshold and how close it is. Based on this data, the contractor may take action to protect the concrete—the contractor might leave formwork in place longer than planned to provide additional insulation to keep temperatures within spec, or the contractor might modify the mix. COMMAND Center provides the contractor with the information necessary to ensure the construction team can take these precautions at the right time.
View and analyze data in the palm of your hand, at the job site
Choose between using the COMMAND Center iOS app for wireless data transmission or using our rugged, handheld Trimble Nomad to collect concrete temperature data at your job site. Any compatible device you use runs the free, powerful COMMAND Center software which allows you to:
- View and analyze peak temperature data for individual sensors or multiple sensors at once.
- View and analyze temperature differentials between sensors.
- Switch between Celsius and Fahrenheit.
- Use the same sensor to measure temperature and evaluate strength.
Collect data continuously and without interruption
COMMAND Center Sensors record data at common, uninterrupted intervals across all sensors so users can easily compare data across multiple sensors at the exact same times for accurate temperature differential data and comparisons.
Our sensors are also preprogrammed and don’t require initialization—construction teams do not even need to connect to the sensor during placement.
Increase precast production rate and quality control
COMMAND Center can be a real advantage to the precast industry. To improve the success and speed of precast element fabrication, precasters use COMMAND Center to monitor concrete temperatures and concrete strength gain throughout the elements during curing. COMMAND Center can also be used to meet specifications for internal temperature monitoring during precast element fabrication.
How Our Customers Use COMMAND Center to Monitor Concrete Temperature
COMMAND Center sensors provided accurate concrete temperature readings during construction of the new Gerald Desmond Bridge, saving the team time and money.
SPS New England used COMMAND Center to record and log temperature data to meet specifications for mass placement and cold weather concrete pours in a historic drawbridge replacement project in Massachusetts.
Crews used COMMAND Center sensors to determine the gradient between the core and surface of the concrete for a mass placement on SH 45/Loop 1 in Austin, Texas.
