Concrete with strength grade of C70 and preparation method thereof
The invention provides concrete with a strength grade of C70 and a preparation method thereof, and belongs to the technical field of concrete and resource recycling. The concrete with the strength grade of C70 is prepared from the following raw materials in percentage by mass: 18 to 19.56 percent of a cementing material, 74 to 75 percent of aggregate, 0.07 to 0.1 percent of a water reducing agent and the balance of water, the cementing material comprises cement, stainless steel slag and mineral powder; the mass of the stainless steel slag accounts for 20-30% of the total mass of the cementing material; the water-binder ratio of the concrete with the strength grade of C70 is 0.3 to 0.35. The concrete with the strength grade of C70 provided by the invention not only has high strength, but also has ultrahigh durability and stability, and meanwhile, the resource reutilization of the stainless steel slag can be efficiently realized.
本发明提供了一种C70强度等级的混凝土及其制备方法，属于混凝土及资源再利用技术领域。本发明提供的C70强度等级的混凝土，由包括如下质量百分比的原料制备而成：胶凝材料18～19.56％，骨料74～75％，减水剂0.07～0.1％和余量水；所述胶凝材料包括水泥、不锈钢渣和矿粉；所述不锈钢渣的质量占胶凝材料总质量的20～30％；所述C70强度等级的混凝土的水胶比为0.3～0.35。本发明提供的C70强度等级的混凝土不仅具有高强度，还具有超高耐久性和稳定性，同时还能够高效实现对不锈钢渣的资源再利用。
