Rebar-Free Concrete Construction (2024-02)¶

To tackle the challenges associated with traditional reinforced concrete structures, such as labor-intensive construction and durability deterioration over time, this paper proposes an innovative concept called rebar-free concrete construction (RFCC) and explores its potential for future development. Three key aspects of RFCC, including materials, structures, and construction technologies, are comprehensively investigated in this study. It reveals that fiber-reinforced concrete is a promising material for RFCC as it addresses challenges related to load-carrying capacity, ductility, and compatibility with construction technologies, and reduces labor and enables construction in extreme conditions, such as lunar construction. In addition, it shows that bio-inspired structures and optimized designs can significantly contribute to RFCC through offering a balance between architectural aesthetics, load capacity, ductility, and construction efficiency. Furthermore, the paper proposes a design path for RFCC and presents its development prospects. In summary, this paper provides a comprehensive understanding of the innovative concept of RFCC and its potential for future developments. By exploring these aspects of RFCC, researchers and engineers can work towards developing sustainable and resilient construction solutions for the future.
