Carbonated water erosion resistant concrete as well as preparation method and application thereof
The invention belongs to the technical field of material concrete, and particularly relates to carbonated water erosion resistant concrete as well as a preparation method and application thereof. The carbonated water erosion resistant concrete is prepared from the following raw materials: ordinary Portland cement, sulphoaluminate cement, fly ash, slag powder, machine-made sand, gravel, water, a water reducing agent, a retarder and a stabilizer, and the stabilizer is prepared by compounding a water-soluble high-molecular polymer and an organosilane water repellent. The carbonated water resistant concrete provided by the invention can keep excellent mechanical properties, impermeability and carbonated water erosion resistance in a carbonated water environment. The method is suitable for engineering application in karst areas or underground water containing corrosive CO2 and other carbonated water environments, and can effectively solve the technical problems that various properties of concrete in the carbonated water environments are degraded, and the safety and durability of concrete structures and materials cannot be guaranteed.
本发明属于材料混凝土技术领域，具体涉及一种抗碳酸水侵蚀混凝土及其制备方法和应用。该抗碳酸水侵蚀混凝土，由包括以下原料制成:普通硅酸盐水泥、硫铝酸盐水泥、粉煤灰、矿渣粉、机制砂、碎石、水、减水剂、缓凝剂、稳定剂，所述稳定剂由水溶性高分子聚合物、有机硅烷类憎水剂复合制备而成。本发明提供的抗碳酸水混凝土，能够在碳酸水环境中能保持优异的力学性能、抗渗性能和抵抗碳酸水侵蚀的能力。适用于岩溶区或含侵蚀性CO2的地下水等碳酸水环境中的工程应用，可有效解决在碳酸水环境中混凝土各项性能退化，混凝土结构及材料安全与耐久性无法保证的技术问题。
