In the construction of ecological retaining walls, the use of low-alkali cement and wood acetate fiber has two main purposes:Improvement of ecological and environmental performance:Use of low-alkali cement: Compared with traditional cement, low-alkali cement has a lower alkaline component. This helps to reduce the alkalinity of the environment around the wall, making the environment around the wall more neutral, providing a more suitable living environment for aquatic plants and animals. In addition, low-alkali cement also helps to reduce the alkali-aggregate reaction that may occur during the cement hardening process, further enhancing the durability and stability of the wall.Addition of wood acetate fiber: Adding wood acetate fiber during the product pressing process can neutralize the alkalinity of cement and further reduce the alkalinity of the wall. This is not only conducive to the survival of aquatic plants and animals, but also enhances the ecological and environmental performance of the wall. The addition of wood acetate fiber also helps to improve the air permeability and water permeability of the wall, and helps the natural circulation and exchange of water.Specific impact on wall performance:Improvement of the environment around the wall: The combined use of low-alkali cement and wood acetate fiber makes the environment around the wall more neutral, providing a more suitable living environment for aquatic plants and animals. This helps to enhance the biodiversity and ecological functions of the wall.Enhanced wall durability: The use of low-alkali cement reduces the possibility of alkali-aggregate reaction, thereby improving the durability of the wall. The addition of wood acetate fiber also helps to improve the crack resistance and impermeability of the wall.Improved drainage: The ecological retaining wall does not require mortar construction during construction, and is directly made of retaining blocks. There is a gravel drainage layer behind the wall to ensure the smooth drainage of the entire wall. This allows water to freely exchange with the soil through the wall, and through the continuous circulation and exchange of water bodies, the water body can achieve the purpose of self-purification.
In summary, the use of low-alkali cement and wood acetate fiber in the construction of ecological retaining walls not only improves the ecological and environmental protection performance of the wall, but also helps to enhance the durability and drainage of the wall. These advantages make ecological retaining walls have broad application prospects in water conservancy projects, transportation projects and other fields.
