Abstract：Silicone sealant is a high-performance sealing material， with good durability， UV resistance， corrosion resistance， high displacement and weather resistance. Due to the excellent performance of silicone sealant， it can play an important role in concrete construction and achieve better sealing effect. In order to continue to develop the performance characteristics and application value of silicone sealant， the paper will analyze its application in concrete construction. The paper first analyzes the performance of silicone sealants. Compared with polyurethane sealants and polysulfide sealants， silicone sealants have better overall performance. Then the construction process of silicone sealant is analyzed， and the precautions in construction are analyzed. The research shows that silicone sealant contains many small processes in the use process， and each process needs to be carried out in strict accordance with the specifications， especially sizing the process requires special attention. Finally， the development of silicone sealant in concrete construction is analyzed. As time goes by， the performance of silicone sealant will become more excellent， and its application effect will become more significant.
