High-strength fiber-reinforced cement-based composite material as well as preparation method and application thereof
The invention belongs to the technical field of building materials, and discloses a high-strength fiber-reinforced cement-based composite material as well as a preparation method and application thereof. The composite material is formed by mixing, by mass, 85%-92% of a dry material and 8%-15% of water and is applied to steel bridge deck pavement, and the dry material comprises cement, fly ash, silicon powder, slag, a water reducing agent, fine sand and fibers. The material provided by the invention has the performance characteristics of high setting speed, high strength, high ductility, low shrinkage and high temperature resistance, and has good cooperative workability with steel.
本发明属于建筑材料技术领域，公开了一种高强度纤维增强水泥基复合材料及其制备方法和应用。该复合材料通过干料和水混合而成，应用于钢桥面铺装中，其中，按质量百分比计，所述干料为85％～92％，水为8％～15％，其中，所述干料包括水泥、粉煤灰、硅粉、矿渣、减水剂、细砂以及纤维。本发明材料具有凝结速度快、高强度、高延性、低收缩、耐高温的性能特点，同时与钢材的协同工作性良好。
