High-ductility ultra-high performance concrete as well as preparation method and application thereof
The invention provides high-ductility ultra-high performance concrete and a preparation method and application thereof, and relates to the technical field of building materials, the high-ductility ultra-high performance concrete comprises the following components by mass: 420-460 parts of cement, 490-520 parts of sand, 280-300 parts of water, 14.5-15.7 parts of calcium sulfate whisker, 36-45 parts of steel fiber, and 11.3-13.2 parts of PE fiber. The ultra-high performance concrete solves the technical problem that the ultra-high performance concrete in the prior art cannot give consideration to high ductility, high compressive strength and high construction performance, and has the advantages of low energy consumption, low carbon emission, low cost and the like; and the technical effects of ultrahigh strength, high durability, high flow state, excellent deformation resistance and better construction performance are also better considered.
本发明提供了一种高延性超高性能混凝土及其制备方法、应用，涉及建筑材料的技术领域，包括按质量份数计的以下组分：水泥420～460份、砂490～520份、水280～300份、硫酸钙晶须14.5～15.7份、钢纤维36～45份，以及PE纤维11.3～13.2份。本发明解决了现有技术中的超高性能混凝土不能较好地兼顾高延性、高抗压强度以及高施工性能的技术问题，达到了不仅具有较低能耗、较低碳排放量以及较低成本等的优势，而且也较好地兼顾了超高强度、高耐久性、高流态、优异的抵抗变形能力以及较佳施工性能的技术效果。
