| Abstract: | Constructions of islands and reefs are of great significance to safeguard rights and interests of our country. However, it is time-consuming, laborious and uneconomical to transport concrete raw materials from the mainland to islands and reefs. Therefore, sea sand concrete made from the existing resources on islands and reefs has become an important building material in the construction of islands and reefs. In this paper, the research on static and dynamic mechanical properties of sea sand concrete materials are summarized and the mechanical properties of fiber reinforced polymer (FRP) bar-sea sand concrete structure are systematically introduced. Meanwhile, it is pointed out that the dynamic mechanical properties of sea sand concrete should be further studied. The recent researches show that sea sand concrete has higher early strength and the final strength is equivalent to ordinary concrete. Reasonable fiber addition significantly improve the mechanical properties of sea sand concrete. Strain rate effect of sea sand concrete is obvious. FRP bar-sea sand concrete structure with its great corrosion resistance can be better used in a wide range of marine environment and it is an important choice for protective structures. The current international situation is more complex, and the reef construction projects may be subject to explosion, penetration and other extreme loads. It can be concluded that the researches on dynamic mechanical properties of sea sand concrete need to be further strengthened. Therefore, the further researches on the impact resistance and anti-explosion performance of FRP bar-sea sand concrete composite structure are of great significance. |
