1results about How to "Erosion effect is good" patented technology

The application belongs to the technical field of material concrete, and particularly relates to a carbonic acid water erosion resistant concrete and a preparation method and application thereof. The carbonic acid water erosion resistant concrete is made of the following raw materials: ordinary Portland cement, sulphoaluminate cement, fly ash, slag powder, machine-made sand, gravel, water, water reducing agent, retarder, stabilizer, wherein the stabilizer is prepared by compounding a water-soluble polymer and an organic silane hydrophobic agent. The carbonic acid water erosion resistant concrete provided by the application can maintain excellent mechanical properties, anti-permeability and carbonic acid water erosion resistance in a carbonic acid water environment. The application is suitable for engineering application in a karst area or a carbonic acid water environment containing erosive CO2, and can effectively solve the technical problems that the performance of concrete in a carbonic acid water environment is degraded, and the safety and durability of the concrete structure and material cannot be guaranteed.
