Description

technical field [0001] The invention relates to the technical field of concrete, in particular to frost-resistant concrete. Background technique [0002] Concrete has also become the material of choice for roads, dams, and bridges, as industrial development and urbanization accelerate. [0003] In winter in alpine regions, in order to ensure the quality of building materials and construction quality, it is generally difficult to carry out building construction in winter, which not only delays the construction period, but also makes it difficult to ensure the quality of the building even if the construction is forced, causing safety hazards. Contents of the invention [0004] The technical problem to be solved by the present invention is to overcome the deficiencies in the prior art and provide a frost-resistant concrete with good anti-freeze effect and low use cost. [0005] In order to solve the problems of the technologies described above, the technical scheme adopted i...
