Anti-crack concrete for shield segment and preparation method of anti-crack concrete
The invention discloses anti-crack concrete for a shield segment and a preparation method of the anti-crack concrete, and belongs to the field of high-performance concrete.The concrete is prepared from, by weight, 430-450 parts of Portland cement, 50-58 parts of fly ash, 540-560 parts of sand, 1140-1160 parts of gravel, 120-140 parts of water, 100-110 parts of gum dipping structure type basalt fiber and 20-23 parts of a water reducing agent; the strength of the shield segment made of the concrete is improved, the crack resistance of the shield segment is high, the crack resistance of the shield segment is guaranteed, and the bearing capacity of a tunnel lining structure is improved.
本发明公开了一种用于盾构管片的抗裂混凝土及其制备方法，属于高性能混凝土领域，本发明混凝土配料按重量份数计包括：硅酸盐水泥430‑450份、粉煤灰50‑58份、砂540‑560份、碎石1140‑1160份、水120‑140份、浸胶结构型玄武岩纤维100‑110份、减水剂20‑23份；利用该种混凝土制成的盾构管片的各强度均有提高，且其抗裂能力强，既保证了盾构管片的抗裂性能又提高了隧道衬砌结构的承载能力。
