Green iron tailing powder concrete with super-strong frost resistance
The invention provides super-strong anti-freezing green iron tailing powder concrete with strength grades of C30 and C40. The concrete is prepared from the following raw materials: cement, iron tailing powder, river sand, common gravels, water and a water reducing agent. In the green iron tailing powder concrete with superstrong frost resistance provided by the invention, the iron tailing powder is used as a mineral admixture to replace 30% of cement, and the content of harmful pores in the concrete is greatly reduced due to the excellent micro-aggregate filling effect of the iron tailing powder, so that the content of harmless pores and less-harmful pores is increased; the internal pore structure of the concrete is optimized to a great extent, so that the concrete achieves high freezing resistance.
本发明提供了一种强度等级为C30和C40的超强抗冻性能绿色铁尾矿粉混凝土，混凝土所用原材料包括水泥、铁尾矿粉、河砂、普通碎石、水、减水剂。本发明提供的超强抗冻性能绿色铁尾矿粉混凝土中，铁尾矿粉作为矿物掺合料取代30％的水泥，铁尾矿粉优良的微集料填充作用大大降低了混凝土内部的有害孔含量，提高了无害孔及少害孔含量，使混凝土内部孔结构在很大程度上得到优化，从而使混凝土达到高抗冻性。
