Ultra-high performance concrete for injection molding of thin-wall component
The invention discloses ultra-high performance concrete for injection molding of a thin-wall component, which is prepared from the following components in parts by weight: 50 to 80 parts of cement, 10 to 40 parts of mineral admixture, 10 to 20 parts of silica fume, 120 to 200 parts of machine-made sand, 18 to 22 parts of water, 1.2 to 1.5 parts of high-performance water reducing agent and the balance of fiber, and the volume content of the fiber is 0.5 to 3 percent. According to the ultra-high performance concrete for injection molding of the thin-wall component, fibers cannot be gathered and wound at the corners of a reinforcing steel bar or a mold, the fibers are evenly distributed, full injection of the concrete is facilitated, and injection when the reinforcing steel bar is configured in the component or the shape is complex can be met.
本发明公开了一种用于注射成型薄壁构件的超高性能混凝土，按重量份重量计，其组分为：水泥50‑80份，矿物掺合料10‑40份，硅灰10‑20份，机制砂120‑200份，水18‑22份，高性能减水剂1.2‑1.5份以及余量的纤维，所述纤维的体积含量0.5％‑3％。本发明提供的一种用于注射成型薄壁构件的超高性能混凝土，其中纤维不会在钢筋或模具拐角处聚集、缠绕，纤维分布均匀，有利于混凝土的注射充满，可满足构件中配置钢筋或形状复杂时的注射。
