Abstract
With the rapid development of civil engineering, high-performance concrete, as a new type of building material, has attracted much attention for its innovative application and prospects. High performance concrete plays an increasingly important role in civil engineering due to its excellent performance characteristics, such as high strength, high durability, good workability, and economy. This article aims to comprehensively explore the innovative application of high-performance concrete in civil engineering and look forward to its future development prospects. This article provides an overview of the basic theory, performance evaluation indicators, and applications of High Performance Concrete (HPC) in civil engineering, while exploring its economic benefits and environmental impacts. Firstly, the article clearly defines high-performance concrete and elaborates on its differences from traditional concrete in terms of performance characteristics, such as higher strength, excellent durability, and good workability. Furthermore, the article provides an in-depth analysis of the composition and preparation of high-performance concrete, including key elements such as the selection and requirements of raw materials, mix design and optimization, and preparation technology and quality control. In terms of performance evaluation, the article systematically introduces strength indicators, durability indicators, workability indicators, and economic indicators, providing scientific basis for performance optimization and application selection of high-performance concrete. Subsequently, the article discussed in detail the application of high-performance concrete in civil engineering, including high-rise buildings, bridge engineering, underground engineering, and marine engineering, demonstrating its broad application prospects and significant technological advantages. Finally, this article analyzes the economic benefits and environmental impacts of the application of high-performance concrete, indicating that it has significant advantages in improving engineering quality, reducing maintenance costs, and reducing environmental pollution. This study not only helps to deepen the understanding of the basic theory of high-performance concrete, but also provides theoretical support and practical guidance for the widespread application of high-performance concrete in civil engineering.
