ABSTRACT
With the acceleration of global climate change and urbanization, the impact of summer high temperatures on concrete construction has become increasingly significant, emerging as one of the critical factors constraining engineering quality. This study focuses on the technical optimization and quality control strategies for concrete construction under summer high-temperature conditions to mitigate the adverse effects of temperature fluctuations on concrete performance and enhance engineering durability. By analyzing key issues such as the hydration reaction rate, moisture evaporation, and shrinkage cracking of concrete under high-temperature conditions, and integrating laboratory simulation experiments with on-site construction monitoring data, a comprehensive solution based on temperature control measures, mix proportion optimization, and curing techniques is proposed. The results indicate that the adoption of low-temperature raw materials, time-segmented pouring, and highly efficient moisture-retaining curing methods can effectively reduce internal temperature rise in concrete and the generation of surface drying shrinkage cracks, while significantly improving compressive strength and long-term stability. Furthermore, this study innovatively introduces an intelligent temperature control system, enabling real-time monitoring and dynamic adjustment of the concrete temperature field, thereby providing technical support for construction under complex environmental conditions. It is concluded that through scientifically sound construction technologies and meticulous quality management, the challenges posed by summer high temperatures can be effectively addressed, ensuring the high-quality construction of concrete structures and providing theoretical foundations and practical references for similar projects.
