| description | The invention relates to CS40 steel fiber reinforced sprayed concrete prepared by utilizing ferrous mill tailings. The CS40 steel fiber reinforced sprayed concrete comprises the following components in percentage by weight: 14.5-17.5% of cement, 2-2.5% of silica powder, 4-5% of fly ash, 25-33% of gravel, 32-40% of ferrous mill tailings, 1.2-2% of steel fibers, 7.5-8.5% of water, 0.30-0.38%of a polycarboxylate superplasticizer and 1.5-2% of an accelerator. According to the sprayed concrete disclosed by the invention, the ferrous mill tailings can replace natural river sand by 100%, exhaustive exploitation of the natural river sand can be effectively reduced, and mine wastes such as the ferrous mill tailings and the like are consumed to the greatest degree by combining with geographical advantages in an iron producing area. Meanwhile, with the adoption of the steel fibers, the tensile strength, breaking strength and adhesive force of the concrete are obviously improved, and the toughness of the structure is gre |
