Temperature Monitoring
TEMPERATURE MONITORING
Temperature monitoring is carried out to measure temperature variations within concrete during the curing process, immediately after concrete placement. Monitoring ensures that hydration heat, temperature gradients, and cooling rates remain within safe limits to prevent thermal cracking and ensure concrete strength development.
Application:
- Mass concrete curing monitoring (piles, pile caps, raft foundations, retaining walls)
- Thermal stress control in large pours
- Structural health and long-term temperature profiling
There are two types of temperature sensors:
a) Thermocouple Sensor
A conventional temperature sensor is a point based temperature measurement. Thermocouples are embedded in concrete at various depths to monitor temperature rise and cooling trends during curing. Widely used for quality control in mass concrete structures such as piles, slabs, and foundations.
b) Distributed Fibre Optic Temperature Sensor
An advanced fibre optic technology that measures temperature continuously along the entire length of an optical cable. DTS systems provide high-resolution temperature profiles throughout the concrete element, enabling early detection of hot spots, uneven hydration, or thermal cracking risks. The system allows real-time, automated data collection and remote monitoring via cloud-based platforms.
This technology is also suitable for Thermal Integrity Profiling (TIP), as its continuous temperature measurement along the entire cable provides a complete profile of the concrete element.
