The research content of this project is to use the biomimetic principle of animal bone growth and special technology to combine self-leveling ultra-high performance concrete with foamed concrete to prepare gradient concrete that is lightweight, anti-crack, and resistant to chemical corrosion in pressure seawater. On the one hand, ultra-high-performance concrete meets the requirements for the use of prestressed reinforced concrete, and can use the very dense characteristics of the concrete to resist the erosion of seawater; on the other hand, the internal foamed concrete can reduce the self-weight of the material itself to meet the needs of oil extraction platforms and other floating and able to move freely; finally, the excellent fire resistance performance of inorganic materials is used to avoid the occurrence or spread of fires.

The huge oil reserves of the ocean world attract countries around the world to explore and exploit them to increase and improve their energy reserves. The construction of offshore oil production platforms, offshore concrete drilling and production platforms, and storage and transportation platforms, and the manufacturing of engineering ships such as ponges, floating docks, and crane ships are necessary projects to realize marine development. Since the world's first concrete offshore oil production platform was built in 1973, after nearly half a century of development, concrete platforms have been used in the development of offshore oil and gas fields with the advantages of versatility, resistance to seawater corrosion, long fatigue life, and low maintenance costs. Rapid development. Carrying out research on the working performance and corrosion laws of inorganic materials in complex marine environments, and improving their environmental adaptability and special properties such as fire prevention, thermal insulation, and corrosion prevention are the main development trend of inorganic material technology for ships and oceans in the future. At present, concrete is used in offshore platform structures all over shallow seas, middle seas and other deep sea and deep sea areas, while floating structures are still mainly made of organic materials.
