Heat-insulating refractory cement-based material suitable for tunnel environment and preparation method of heat-insulating refractory cement-based material
The invention discloses a heat-insulating refractory cement-based material suitable for a tunnel environment and a preparation method thereof, and belongs to the technical field of building materials. The thermal insulation mortar is prepared from the following raw materials and components in parts by weight: 100 parts of cement, 42.6 to 85.2 parts of sand, 20.8 to 23.4 parts of expanded perlite, 1.7 to 10.3 parts of silicon dioxide aerogel, 1.8 to 2.3 parts of basalt fiber, 2 parts of a water reducing agent, 0.5 part of defoaming powder and 55 parts of water. The heat-insulating refractory cement-based material has excellent compressive strength and high-temperature burst resistance, is not prone to peeling and fatigue failure under load and vibration generated by surface pressure and vehicle cyclic load, solves the problems of low strength and poor durability of current tunnel fireproof coatings, and can meet the long-term fire-resistant requirements of tunnel structures.
本发明公开了一种适用于隧道环境的隔热耐火水泥基材料及其制备方法，属于建筑材料技术领域。其原料及各组分重量比为：水泥100份、砂42.6‑85.2份、膨胀珍珠岩20.8‑23.4份、二氧化硅气凝胶1.7‑10.3份、玄武岩纤维1.8‑2.3份、减水剂2份、消泡粉0.5份、水55份。本发明隔热耐火水泥基材料具有优异的抗压强度与抗高温爆裂性能，不易在地表压力与车辆循环荷载产生的荷载与振动下产生剥落和疲劳破坏，解决了当今隧道防火涂料强度低，耐久性差的问题，可满足隧道结构长期的抗火要求。
