The complex thermal behaviour of the mass concrete and the risk associated when it is not regulated properly, demands implementation of continuous temperature monitoring.
To establish a continuous temperature monitoring system, embedded temperature sensors are used, which at the time of pouring are placed inside at different depths, to provide real-time data over the critical curing period, capturing peak temperatures, temperature gradients (core vs surface), rate of cooling, and overall temperature history.
Continuous temperature monitoring allows engineers to take necessary steps towards regulation of the thermal gradient.
Guidance from ACI’s mass concrete practice encourages instrumentation for mass placements to monitor thermal behavior and manage risks.
In addition, modern practices implement wireless sensors or data loggers, which allows for continuous monitoring without the need of manual checks, improving the safety, efficiency, and record-keeping.
