Problems solved by technology

[0002] Concrete is one of the most used building materials at present. Since its invention in 1824, it has made great contributions to human progress and economic development. It has become a commonly used reinforcement material for mountain slopes. However, the existing concrete has anti-cracking performance The impermeability and impermeability are still not ideal, and the concrete baffles made of it will crack and have poor durability when applied to mountain slopes and other places, which limits the application of concrete baffles

Description

technical field [0001] The invention relates to the technical field of concrete, in particular to a special concrete baffle for mountain slopes. Background technique [0002] Concrete, as one of the most widely used building materials at present, has made great contributions to human progress and economic development since its invention in 1824. It has become a commonly used reinforcement material for mountain slopes, but the existing concrete has crack resistance. The anti-permeability and impermeability are still not ideal, and the concrete baffles made of it will crack and have poor durability when applied to mountain slopes and other places, which limits the application of concrete baffles. Contents of the invention [0003] Based on the technical problems existing in the background technology, the present invention proposes a special concrete baffle for mountain slopes, which has excellent crack resistance, and good impermeability and durability. [0004] The present...
