Low-dosage steel fiber modified powder concrete
The invention discloses low-dosage steel fiber modified powder concrete which comprises the following raw materials in parts by weight: 600-1000 parts of cement, 150-300 parts of active mineral admixture, 60-100 parts of inert admixture, 900-1300 parts of sand, 26-35 parts of a water reducing agent, 135-160 parts of water, 30-100 parts of extra-fine steel fibers and 7-12 parts of a corrosion inhibitor. According to the low-dosage steel fiber modified powder concrete, provided by the technical scheme of the invention, the extra-fine steel fibers with the diameters being smaller than 0.13 mm and the lengths being 6-12 mm are adopted for replacing common steel fibers, therefore on the one hand, the mechanical property of the concrete is improved, on the other hand, the additive amount of steel fibers in the concrete is further reduced, and the production cost of the low-dosage steel fiber modified powder concrete is reduced; besides, the low-dosage steel fiber modified powder concrete is relatively low in the wholesale cost, good in the fiber distribution uniformity, high in fracture resistance and shock resistance and is suitable for popularization and application in the constructional engineering industry.
