Super-early-strength UHPC premix for rush repair of airport runway
The invention relates to the technical field of traffic engineering materials, and discloses a super-early-strength UHPC premix for airport runway first-aid repair, which comprises a component A and a component B. The component A comprises ordinary Portland cement quartz sand levigated mineral powder, floating bead inorganic early strength agent F10 superplasticizer. The compound inorganic early strength agent promotes the early hydration speed of ordinary Portland cement, the floating beads are added to reduce the viscosity of the material and improve the pore structure and pore distribution of a hydration product, the water-retaining agent is added to adjust the water consumption required by each stage of cement hydration so as to correct an exothermic temperature curve, and the copper-plated steel fibers are added to greatly improve the toughness of the material. Ordinary Portland cement is used as a main cementing material, graded quartz sand is used as an aggregate, mineral micro powder is used as an active mixed material, and a polycarboxylic acid water reducing agent and the like are added to prepare the super-early-strength UHPC premix for rush repair of the airport runway.
本发明涉及交通工程材料技术领域，且公开了一种用于机场跑道抢修的超早强UHPC预混料，包括A组份和B组份，A组份包括普通硅酸盐水泥石英砂磨细矿粉漂珠无机早强剂F10高效减水剂该一种用于机场跑道抢修的超早强UHPC预混料，复配无机早强剂促进普通硅酸盐水泥早期水化速度、添加漂珠降低材料本身的粘滞性、改善水化产物的孔结构和孔分布、添加保水剂调整水泥水化各阶段所需用水量进而修正放热温度曲线，添加镀铜钢纤维以大幅度提升材料韧性，以普通硅酸盐水泥为主要胶凝材料、以级配石英砂为集料，以矿物微粉为活性混合材料，添加聚羧酸减水剂等，制成用于机场跑道抢修的超早强UHPC预混料。
