11.Intelligent Temperature Control and Anti-cracking Digital Management Technology for Mass Concrete: Current Cases and Full-life Cycle Intelligent Monitoring Trends

1. Current Application Status
With the continuous expansion of large-scale infrastructure such as water conservancy dams, super-high-rise foundation slabs and large municipal platforms, mass concrete construction has become a key link restricting structural safety. At present, most large projects adopt IoT intelligent temperature measuring systems and automatic water cooling equipment to monitor and control the hydration heat temperature of mass concrete in real time. The intelligent platform can collect temperature data of different structural layers, realize remote data viewing and automatic cooling adjustment, and effectively avoid temperature cracks caused by excessive internal and external temperature differences. This digital management mode has been widely verified in domestic super projects and has gradually begun to be applied in overseas large-scale hydraulic engineering.

2. Existing Technical Shortcomings
Although the current intelligent temperature control system improves the refinement level of construction management, there are still obvious industry pain points. Most monitoring platforms form independent data islands, failing to realize data interconnection with construction progress, quality inspection and later operation and maintenance data. The temperature early warning mechanism is relatively simple, relying mainly on fixed threshold judgment, lacking intelligent prediction of temperature change trends, resulting in delayed crack early warning. In addition, the temperature control scheme still relies on artificial experience calibration, which cannot dynamically adapt to complex weather and variable on-site construction conditions, leading to inconsistent control accuracy in different projects.

3. Future Development Trends
The future development direction of mass concrete management is full-life cycle intelligent digital supervision based on AI and sensing integration. By introducing machine learning algorithms, the system can simulate the hydration heat release law of concrete in advance, predict temperature difference changes and automatically generate optimal cooling schemes. Embedded intelligent sensing concrete technology will realize synchronous monitoring of internal temperature, stress and strain of structures, forming multi-dimensional safety data perception. In the long run, the industry will build a unified digital database for mass concrete construction to realize intelligent closed-loop management of construction, detection, early warning and operation maintenance.

4. Overseas Engineering Promotion Value
This set of digital temperature control and anti-cracking technology is highly adaptable to overseas large-scale hydraulic engineering, port foundation and large municipal complex projects. It can solve the problems of backward on-site management and high manual dependence in overseas construction sites, standardize the mass concrete construction quality control system, and form a complete set of intelligent construction solutions for export. The integrated service mode of intelligent sensing modules and special concrete matching can effectively improve the safety and durability of overseas large concrete structures.

Conclusion

Digital intelligent temperature control effectively solves the cracking risk of mass concrete caused by hydration heat. With AI prediction and full-life cycle data interconnection, the technology will realize unmanned and refined construction management. It provides standardized and replicable digital construction standards for global large-scale concrete infrastructure quality improvement.
