Abstract

With the continuous expansion of the construction scale of water conservancy and hydropower projects, the control of concrete construction quality has become a key factor affecting the safety and durability of the projects. The application of temperature control and crack prevention technology in concrete construction, especially in water conservancy and hydropower projects, is of great significance for improving the stability of concrete structures and extending their service life. By analyzing the stress and crack problems caused by temperature changes during the concrete construction process and combining with practical engineering cases, this paper discusses the implementation methods and effects of temperature control and crack prevention technology. Reasonable temperature control measures can effectively prevent the occurrence of cracks and improve the overall quality of the project. This paper also summarizes common temperature control methods and equipment, and looks forward to the development trend of temperature control and crack prevention technology in the future.
