Researchers at UST Inc. Present Strategies to Enhance the Strength and Durability of String Transport Supports
The authoritative Indian scientific publication, ISAR Journal of Multidisciplinary Research and Studies, has recently featured a research by Anatoli Unitsky and an expert from Unitsky String Technologies Inc.
Building uST transport infrastructure complexes requires load-bearing structures to be more reliable, particularly in areas with harsh climates.
Preventing thermal cracks in concrete during the hardening and operational stages is one of the main challenges in the construction of string rail transport supports. These cracks can arise due to temperature gradients, the emission of heat from the concrete, and significant dynamic loads from vehicles traveling at speeds of up to 500 km/h or more.
The scientific article outlines a comprehensive approach to address this issue, offering several effective methods:
1. Optimizing Concrete Composition: Using binders that generate less heat when mixed with special additives is recommended. This strategy helps control the setting speed of the concrete while reducing internal stresses.
2. Reinforcement Use: Reinforcing uST structures with steel is essential. Selecting concrete and reinforcement with comparable thermal expansion coefficients is essential because it reduces internal stress and lowers the risk of cracks during temperature changes.
3. Modern Thermal Monitoring: To ensure continuous temperature control, the implementation of Internet of Things (IoT) systems is advised. Sensors integrated into the structure provide real-time data, allowing for timely adjustments to heating or cooling mode and preventing critical temperature drops.
4. Adaptive Construction Techniques: In low-temperature conditions, the use of the “thermos” method of concrete curing is effective. This method helps maintain the thermal balance of the concrete, enhancing the quality of its hardening.
As noted in the article, this set of measures can significantly increase the concrete’s thermal stability against cracking and ensure the durability and reliability of string transport supports, even in extreme climatic conditions.
