Concrete, and preparation method and application thereof
The invention belongs to the technical field of building materials, and particularly relates to concrete, and a preparation method and application thereof. The concrete provided by the invention comprises, by weight, 1 part of cement; 0.9 to 1.1 parts of fine aggregate; 0.2 to 0.4 part of quartz powder; 0.1 to 0.3 part of silica fume; 0.03 to 0.04 part of a water reducing agent; 0.003 to 0.0075 part of polypropylene fiber; and 0.18 to 0.26 part of water. The water-binder ratio is (0.13-0.24): 1. The normal-temperature compressive strength of the concrete provided by the invention is greater than 120 MPa, and the concrete has excellent mechanical properties; and the residual mechanical property after high temperature is excellent. In addition, after re-curing, the concrete provided by the invention is relatively high in recovery capability.
本发明属于建筑材料技术领域，具体涉及一种混凝土及其制备方法和应用。本发明提供的混凝土，包括以下重量份数的组分：水泥1份；细骨料0.9～1.1份；石英粉0.2～0.4份；硅灰0.1～0.3份；减水剂0.03～0.04份；聚丙烯纤维0.003～0.0075份；水0.18～0.26份；水胶比为(0.13～0.24)：1。本发明提供的混凝土的常温抗压强度＞120MPa，具有优良的力学性能；而且高温后残余力学性能优良。另外，经再养护后，本发明提供的混凝土的恢复能力较高。
