Modern infrastructure projects like dams, heavy foundations, large mat slabs, high-rise building footings, bridges, retaining walls increasingly rely on advanced temperature monitoring systems because of the scale, complexity, and long-term performance requirements.
Advanced monitoring systems like embedded sensors, data loggers, wireless connectivity provides real-time continuous temperature data for core, mid-depth, and surface zones.
Moreover, with increasing complexity such as combined loads, strict durability requirements, aggressive environmental exposure the margin for error is now lower than ever.
For contractors, engineers, and clients, reliance on modern monitoring tools allows them to reduce risks, implement different strategies to preserve the long term durability of the concrete structures.
Given all this, advanced temperature monitoring in mass concrete is no longer optional, it is becoming the standard for best-practice, safety-conscious, long-term construction.
Mass Concrete temperature Monitoring system
Mass concrete temperature monitoring device developed by Vedantrik technologies is an advanced temperature monitoring and data logging system specifically designed for mass concrete applications like raft, foundations, hot blocks and other mass concretes to prevent thermal stresses and micro cracking.
Wire length Challenges in Mass Concrete Temperature Monitoring
In mass concrete applications, temperature sensors are typically embedded at multiple levels — the top, middle, and bottom of the pour — to accurately monitor temperature differentials during curing. However, in high-rise building foundations, the raft thickness can reach up to 3 meters or more, creating significant wirelength challenges.
As the sensors are placed deeper within the concrete, the distance between the sensors and the data loggers (which are usually installed at a controlled, accessible location) can exceed 5 meters. This extended wirelength can lead to inaccurate or higher temperature readings.
The commonly used RTD (Resistance Temperature Detector) thermocouples in concrete temperature monitoring are typically accurate only up to a cable length of approximately 5 meters. Beyond this distance, the increase in lead resistance can result in elevated or higher temperature readings.
This is particularly problematic because the lead resistance is non-linear and not directly proportional to the cable length, making it difficult to apply standardized correction factors. Consequently, extended cable lengths introduce a significant source of error in temperature measurements.
But the device developed by vedantrik technologies for mass concrete temperature monitoring can give accurate temperature readings even if wirelengths are above 100 meters with accuracy of +/- 1 degree celsius.
The device logs temperature data at user-defined intervals, with a standard recording interval of 30 minutes. The system utilizes high accuracy sensors, which are embedded in the concrete, during casting and remain in place throughout the curing process.
These sensors feed temperature data to the device’s internal storage, which can be accessed later wirelessly using mobile phone or laptop via wifi, the device supports Wi-Fi connectivity, allowing users to access and monitor data in real time through a PC, laptop, or mobile device. By providing accurate and timely temperature data, the system supports informed decisions regarding concrete strength development, enabling optimized construction schedules, timely formwork removal, and improved quality control in mass concrete applications.
