Sprayable ultrahigh-toughness cement-based composite material as well as preparation method and application thereof
The invention provides a sprayable ultrahigh-toughness cement-based composite material as well as a preparation method and application thereof. The sprayable ultrahigh-toughness cement-based composite material is prepared from the following components in parts by mass: 30 to 50 parts of a colloidal material, 25 to 30 parts of quartz sand, 0.2 to 0.5 part of a water reducing agent, 3 to 7 parts of an accelerator, 9 to 16 parts of water and high-performance fibers, the volume mixing amount of the high-performance fibers is 1-2% of the total volume of the sprayable ultrahigh-toughness cement-based composite material; the colloidal material comprises cement, fly ash, calcined clay, limestone and magnesium oxide. The sprayable ultrahigh-toughness cement-based composite material can quickly repair old cracked tunnels, does not hinder normal passage of tunnel vehicles, effectively enhances tunnel toughness, improves disaster prevention and crack resistance, is low-carbon and environment-friendly, and saves energy consumption.
本发明提供了一种可喷射超高韧性水泥基复合材料及其制备方法与应用。所述可喷射超高韧性水泥基复合材料按照质量份数计包括：30～50份胶体材料，25～30份石英砂，0.2～0.5份减水剂，3～7份速凝剂，9～16份水以及高性能纤维；所述高性能纤维的体积掺量为所述可喷射超高韧性水泥基复合材料总体积的1‑2％；所述胶体材料包括水泥、粉煤灰、煅烧粘土、石灰石以及氧化镁。所述可喷射超高韧性水泥基复合材料不仅能够快速修补老旧开裂隧道，不妨碍隧道车辆的正常通行，有效增强隧道韧性，提升防灾抗裂的能力，而且低碳环保，节约能源消耗。
