| Abstract: |
| Silane coatings provide a variety of superior surface protection to cement substrates by corrosion transport inhibition and crystallization induction， improving the durability and safety reliability of concrete structure. The physical and chemical properties of silane coatings， the binding mechanisms for cementitious materials were summarized， while the effectiveness of silane coatings in improving the durability of cementitious materials were comprehensively reviewed. Additionally， the main issues and future development trends in engineering applications were analyzed and proposed， aiming to provide significant theoretical guidance and engineering reference for the in-depth research and application of durability protection of cementitious material. |
