Jet type high-toughness fiber reinforced cement-based composite material and preparation method thereof
The invention discloses a jet type high-toughness fiber reinforced cement-based composite material and a preparation method thereof, and belongs to the technical field of material preparation. The invention provides a jet type high-toughness fiber reinforced cement-based composite material, which is prepared from the following raw materials in parts by mass: 320 to 400 parts of coarse aggregate, 220 to 260 parts of fine aggregate, 90 to 110 parts of cement, 40 to 50 parts of water, 10 to 15 parts of modified fiber, 5 to 10 parts of zeolite powder, 5 to 10 parts of polymerizing agent, 4 to 7 parts of accelerator and 2 to 5 parts of water reducing agent. The chemical bonding force of the fiber and the concrete interface is improved, meanwhile, the mechanical property of a hydration product at the interface is improved, the dispersity of the fiber in the concrete is improved, and the stress transmission and dispersion capacity of the fiber is effectively enhanced, so that the mechanical property and durability of the fiber concrete are enhanced.
本发明公开了一种喷射型高韧性纤维增强水泥基复合材料及其制备方法，属于材料制备技术领域。本发明提供了一种喷射型高韧性纤维增强水泥基复合材料，所用原料以质量份数计包括：粗骨料320‑400份、细骨料220‑260份、水泥90‑110份、水40‑50份、改性纤维10‑15份、沸石粉5‑10份、聚合剂5‑10份、速凝剂4‑7份和减水剂2‑5份，通过对纤维进行改性，提高了纤维与混凝土界面的化学粘结力，同时提高界面处水化产物的力学性能，并改善纤维在混凝土中的分散性，有效增强纤维传递与分散应力能力，从而增强纤维混凝土的力学与耐久性能。
