The newly introduced temperature control system is a device that can secure the required strength with minimal curing insulation without separate heat curing under the condition of a daily minimum temperature of -5℃ or higher. Cold-resistant concrete is a key material that maintains the quality and stability of structures at construction sites during winter. The initial production temperature plays a major role in strength development and workability improvement, making temperature control of each material and mixing water important.
During pouring, ultra-small wireless sensors are embedded inside the concrete to monitor the internal heat generated during the curing process in real time. The related data is transmitted to the central quality management system, allowing on-site workers and quality managers to manage temperature changes for 14 days after pouring, thereby enhancing the safety of the structure and minimizing quality variations. This system is applied not only to cold-resistant concrete but also to summer concrete, solving issues of strength reduction and workability problems caused by high temperatures in summer, and is expected to reliably supply high-quality concrete throughout all four seasons.
Ajoo Industrial expects that this system will simplify the process without insulation equipment, reduce safety accidents by eliminating the need to operate heat curing equipment, and reduce costs. Starting with -5℃ cold-resistant concrete, Ajoo Industrial plans to launch product lines for -10℃ daily minimum temperature and 10℃ transitional season products by next year.
An Ajoo Industrial official said, "The introduction of the automatic temperature control system will be an important turning point in the special concrete market, which is expanding recently in the construction industry," adding, "In the future, by integrating artificial intelligence (AI) and the Internet of Things (IoT) technologies, we plan to realize digitalization of quality control to strengthen the soundness of cold-resistant concrete and enable precise management."
