Application of ultra-high performance concrete wet joint technology in marine environment

Because the salt content in seawater is relatively high, it also contains other salt-containing components such as chloride salts. In the process of construction of sea-related projects, because these construction projects must be in contact with sea water for a long time, they are subject to greater impact and erosion by sea water. Researching new concrete materials that are more stable and durable has become the main research task and direction of researchers, and this new type of material can solve the problems and deficiencies of the original materials to a certain extent. The UHPC joint bridge first needs to construct the concrete structure at both ends of the beam, and at the same time build the steel bars into the prefabricated formwork, and finally use UHPC materials to connect at the joints. The material selection of the caulking agent should be given priority. The materials with good viscosity and strength after adding various additives, and at the same time, the tensile, compressive, and flexural experiments are carried out to comprehensively select various additives to achieve a scientific ratio. Ultra-high performance concrete can have great stress performance in structure. The design of the ultra-high performance concrete structure is very different from the previous ordinary concrete, and the design is independent and innovative. Through experiments, it can be concluded that when constructing and constructing coastal engineering buildings, setting the permanent formwork of high-performance concrete as the appearance of the construction project can increase the durability and stability of the construction project. The use of this ultra-high performance concrete material will surely become the main raw material used in China’s future construction and will play a very important role in improving the quality and robustness of the building.
