Abstract

The plateau environment is prominently characterized by low-temperature freeze-thaw cycles, strong ultraviolet radiation, large day-night temperature differences, and low air pressure. These factors collectively pose severe challenges to the structural stability and durability of traditional concrete. Low-temperature freeze-thaw cycles cause repeated freezing and expansion of pore water inside concrete, leading to continuous propagation of microcracks; strong ultraviolet radiation accelerates the photolysis and carbonation of cement hydration products, resulting in surface pulverization and decreased bonding strength; large day-night temperature differences induce periodic thermal expansion and contraction of materials, accumulating fatigue stress and causing the initiation of macroscopic cracks; and the low air pressure environment accelerates water evaporation, easily causing early setting and cracking of the concrete surface, further reducing material strength. Plastic concrete, as a new composite material where synthetic resin replaces cement, demonstrates unique advantages in plateau water conservancy projects and infrastructure construction due to its low deformation modulus, high impermeability, and good environmental adaptability. For example, plastic concrete cutoff walls have become a common and effective method in earth-rock dam danger removal and reinforcement projects. This paper reviews the regulatory mechanism of synthetic resin content on plastic concrete performance and sorts out the engineering adaptation paths suitable for the plateau environment, aiming to provide a theoretical reference for engineering material design in cold and high-altitude regions.
