ABSTRACT
With the acceleration of urbanization and the development of construction technology, high-rise buildings have gradually become an important component of modern urban construction. High-performance concrete (HPC), due to its excellent mechanical properties, durability, and adaptability in construction, has been widely applied in high-rise building projects. This study focuses on the application and construction technology of HPC in high-rise buildings, aiming to explore its preparation process, performance optimization, and key construction technologies. Through a systematic review of relevant domestic and international literature and analysis of practical engineering cases, this research combines experimental studies with numerical simulations to investigate the mix design, rheological characteristics, strength development patterns, and technical points in pumped construction of HPC. The results indicate that by reasonably adjusting the composition of cementitious materials and admixture ratios, the workability and long-term durability of concrete can be significantly improved. Simultaneously, pumpable construction techniques optimized for the specific features of high-rise building construction effectively reduce the risk of pipeline blockages and enhance construction efficiency. The innovation of this study lies in proposing a formulation scheme for HPC suitable for super-high-rise buildings and developing a corresponding intelligent construction monitoring system, providing technical support for quality control of concrete under complex working conditions. The research findings not only offer theoretical foundations and technical guarantees for the application of HPC in high-rise buildings but also hold significant implications for promoting the development of green building materials.
