The research content of this project is to utilize the bionics principles of animal bone growth and special processes, combining self-leveling ultra-high performance concrete with foamed concrete to prepare a lightweight, crack-resistant, and pressure-resistant gradient concrete that can withstand chemical corrosion from seawater. On one hand, the ultra-high performance concrete meets the requirements for prestressed reinforced concrete, which can be utilized for its very dense characteristics to resist erosion by seawater; on the other hand, the internal foam concrete can reduce the weight of the material itself to meet the needs of floating platforms such as oil extraction platforms that are capable of free movement; finally, utilizing the excellent fireproof properties of inorganic materials, it prevents fires from occurring or spreading. The vast oil reserves in the ocean world attract countries around the world to explore and exploit them to increase and enhance their energy reserves. The construction of offshore oil extraction platforms, off-shore concrete drilling and production platforms, and storage and transportation platforms, as well as pontoon boats, floating dry docks, The manufacture of engineering vessels such as crane ships is a necessary engineering task for achieving marine development. Since the first concrete offshore oil platform was built in the world in 1973, after nearly half a century of development, concrete platforms have rapidly gained popularity in the development of offshore oil and gas fields due to their multifunctionality, resistance to seawater corrosion, long fatigue life, and low maintenance costs. Conducting research on the working performance and corrosion behavior of inorganic materials in complex marine environments, enhancing their environmental adaptability, and improving special properties such as fire resistance, insulation, and anti-corrosion are the main trends in future technology for inorganic materials used in shipbuilding and marine applications. Currently, the application of concrete in ocean platform structures has spread across shallow seas, mid-depth seas, and deep sea areas, while floating structures still mainly use organic materials.
