Ultra-high performance concrete bridge deck and production process thereof
The invention discloses an ultra-high performance concrete bridge deck and a production process thereof, and the ultra-high performance concrete bridge deck comprises the following components in parts by weight: 100 +/-5 parts of cement, 31 +/-3 parts of silica fume, 38 +/-4 parts of fly ash, 169 +/-6 parts of quartz sand, 25 +/-7 parts of steel fiber, 2 +/-1 part of admixture and 29 +/-3 parts of water. The production process comprises the following steps: 1) stirring: stirring by adopting a speed-adjustable forced stirrer to form slurry; (2) forming: pouring the slurry from one side of a mold, standing and solidifying to form an ultra-high-performance concrete blank after pouring is completed, and removing the ultra-high-performance concrete blank from the mold after solidification forming; 3) curing: curing the ultra-high performance concrete green body as required. The ultra-high performance concrete green body has the advantages of high strength, high elastic modulus, high impermeability and capability of ensuring the safety and stability of rail travelling.
本发明公开了一种超高性能混凝土桥面板及其生产工艺，其组份以及重量配比为，水泥100±5份、硅灰31±3份、粉煤灰38±4份、石英砂169±6份、钢纤维25±7份、外加剂2±1份、水29±3份。生产工艺包括以下步骤，1）搅拌：采用可调速强制式搅拌机进行搅拌，形成浆料；2）成型：将所述浆料从模具的一侧开始浇筑，浇筑完成后搁置凝固形成超高性能混凝土坯体，凝固成型后将超高性能混凝土坯体从模具中脱出；3）养护：按要求对超高性能混凝土坯体进行养护。本发明具有高强度、高弹性模量、高抗渗性能以及保证轨道行车的安全性和平稳性的优点。
