High‐performance Composite Structural Concrete

This chapter discusses the development and application of high-performance composite structural concrete materials in China. It covers cement–asphalt composite mortar for high-speed railway track slabs, functionally graded shield tunnel segment concrete, anti-penetration and anti-explosion concrete, and high-strength lightweight aggregate concrete. The chapter presents innovative design principles, performance optimization techniques, material preparation methods, structural design approaches, and construction technologies for these specialized concrete materials. Innovative solutions are provided to address challenges in durability, strength, volume stability, and construction efficiency. The successful application of these advanced materials in major infrastructure projects demonstrates their significant technical, economic, and social benefits.
