Abstract:Taking Miyun iron tailings as raw materials,the tailing concrete with ultrahigh strength was prepared by adopting micro-ball effects between different materials in gradient grinding process.The product has good stability and durability and owns total ratio of iron tailings up to 70% in weight,average compressive strength of 109.13 MPa and flexural strength of 15.53 MPa.
Keywords:Iron ore tailing  Gradient grinding  Micro-ball effect  Ultra-high strength concrete
