Special superfine powder-containing concrete for bridge prefabricated component and preparation method thereof
The invention relates to the technical field of building materials, and particularly provides special superfine powder-containing concrete for a bridge prefabricated component and a preparation method of the special superfine powder-containing concrete. The concrete is prepared from the following raw materials in parts by weight: 300 to 500 parts of cement, 1200 to 1600 parts of coarse aggregate, 400 to 550 parts of lightweight aggregate, 100 to 150 parts of water, 50 to 100 parts of superfine powder, 10 to 70 parts of admixture and 10 to 30 parts of reinforcing aid. By modifying the surface of the reinforcing aid with the organic aid and specifying the relative amounts of the concrete, the superfine powder and the admixture, the concrete has excellent mechanical properties and workability, does not corrode a metal base material, and can delay the corrosion phenomenon of the metal base material, so that the service life of the concrete is prolonged, and the service life of the concrete is prolonged. And the manufacturing and use environment requirements of bridge prefabricated parts are met.
本发明涉及建筑材料技术领域，具体提供了一种含专用超微粉的桥梁预制构件用混凝土及其制备方法；按照重量份计，所述混凝土的制备原料包括：水泥300‑500份、粗骨料1200‑1600份、轻骨料400‑550份、水100‑150份、超微粉50‑100份、外加剂10‑70份、增强助剂10‑30份。通过使用有机助剂修饰增强助剂的表面，规定混凝土、超微粉和外加剂的组分原料的相对用量等，使本申请的混凝土具有优异的力学性能和和易性，对金属基材无腐蚀且能延缓金属基材的腐蚀现象，符合桥梁预制构件的制作和使用环境要求。
