Study on flexible structure with waterproof, breathable and thermal insulation in concrete construction

with the development scale of urbanization construction in China, the technical standard of concrete construction is getting higher and higher. It is the key breakthrough direction of technology to strengthen waterproof and air permeability in concrete construction. Nonwoven formwork lining technology is a way to improve the impermeability of concrete structure surface to achieve the overall durability of concrete structure. Some hydrated residual water and large bubbles of concrete at a certain depth of surface layer are discharged, thus reducing the water-cement ratio of concrete, realizing the compactness of structural surface, increasing the strength and hardness of concrete surface, and achieving the purpose of improving the performance of surface concrete. This paper mainly analyzes the flexible structure of waterproof, breathable and heat preservation, and puts forward personal views and viewpoints.
