Steam-curing-free ultra-high performance concrete for bridge pier body and preparation method of steam-curing-free ultra-high performance concrete
The invention discloses steam-curing-free ultra-high performance concrete for a bridge pier body and a preparation method of the steam-curing-free ultra-high performance concrete. The concrete is prepared from the following components in parts by weight: 566 to 693 parts of cement, 332 to 426 parts of auxiliary cementing material, 600 to 700 parts of fine aggregate, 700 to 800 parts of coarse aggregate, 156 to 195 parts of steel fiber, 25 to 34 parts of water reducing agent and 164 to 184 parts of water. The preparation method comprises the following steps: mixing the cement, the auxiliary cementing material, the fine aggregate and the coarse aggregate; uniformly mixing water and a water reducing agent, and then adding the mixture; finally, adding steel fibers and stirring; under the standard curing condition, the steam-curing-free ultra-high performance concrete for the bridge pier body is obtained. The working performance and the physical and mechanical properties of the ultra-high performance concrete can reach the physical and mechanical technical requirement standard of a bridge pier body.
本发明公开了一种桥梁墩身用免蒸养超高性能混凝土及其制备方法，该混凝土包括566～693重量份的水泥、332～426重量份的辅助胶凝材料、600～700重量份的细骨料、700～800重量份的粗骨料、156～195重量份的钢纤维、25～34重量份的减水剂、164～184重量份的水。制备方法如下：将水泥、辅助胶凝材料与细骨料、粗骨料混合；将水与减水剂混合均匀后加入混合料；最后加入钢纤维进行搅拌；在标准养护条件下，得到桥梁墩身用免蒸养超高性能混凝土。本发明的超高性能混凝土工作性能与物理力学性能可以达到桥梁墩身的物理力学技术要求标准。
