High-performance concrete shield segment and preparation method thereof
The invention discloses a high-performance concrete shield segment and a preparation method thereof, and belongs to the field of subway shield segment production. The shield segment comprises Portlandcement, fly ash, broken stone, river sand, machine-made sand, mixing water and a high-performance water reducing agent. By adding the machine-made sand into the concrete, the early strength of the concrete can be improved, the compactness of the concrete is improved, and the concrete has good permeation resistance. Moreover, the raw materials of the machine-made sand are easy to obtain, and the material cost is reduced to a certain extent.
本发明公开了一种高性能混凝土盾构管片及其制备方法，属于地铁盾构管片生产领域。本发明管片由硅酸盐水泥、粉煤灰、碎石、河砂、机制砂、拌和用水和高性能减水剂组成。本发明通过在混凝土中添加机制砂，可有助于提高混凝土的早期强度，提高混凝土的密实度，具有良好的抗渗透能力。并且本发明提供的机制砂原料容易获得，一定程度降低了材料成本。
