Composition for ultra-high performance concrete, ultra-high performance concrete as well as preparation method and application of ultra-high performance concrete
The invention relates to the technical field of building materials, and discloses a composition for ultra-high performance concrete, the ultra-high performance concrete and a preparation method and application thereof.The composition contains cement, silica fume, fine aggregate, threaded steel fibers, a water reducing agent and water, the threaded steel fibers are formed by spirally winding at least two steel wires, and the fine aggregate is formed by spirally winding at least two steel wires; the average diameter d of the thread type steel fiber is 0.2 to 0.4 mm, and the tensile strength of the thread type steel fiber is 1100 to 1600 MPa. The ultra-high performance concrete provided by the invention has stronger cohesiveness with a matrix, and has more excellent mechanical properties and deformation properties. And the method has good economic benefits and wider application prospects.
本发明涉及建筑材料技术领域，公开了一种超高性能混凝土用组合物、超高性能混凝土及其制备方法和应用，所述组合物中含有：水泥、硅灰、细骨料、螺纹型钢纤维、减水剂和水，所述螺纹型钢纤维由至少两股钢线螺旋缠绕形成，且所述螺纹型钢纤维的平均直径d为0.2‑0.4mm，抗拉伸强度为1100‑1600MPa。本发明提供的超高性能混凝土与基体粘结性更强，具有更加优异的力学性能与变形性能。具有良好的经济效益以及更广阔的的应用前景。
