Rapid replacement material for ballastless track bed of high-speed railway
The invention discloses a quick-change material for a ballastless track bed of a high-speed railway. The quick-change material is prepared from the following raw materials in parts by weight: 100 parts of a cementing material, 150-300 parts of coarse aggregate, 100-200 parts of fine aggregate, 0-30 parts of a mountain flour mineral admixture, 5-12 parts of a polymer, 5-20 parts of an expanding agent, 5-10 parts of an elastic toughening agent, 0.5-2 parts of a working performance regulator, 0-1 part of a defoaming agent, 0-1 part of an air entraining agent and 30-200 parts of water, the preparation method specifically comprises the following steps: (1) weighing the raw materials; and (2) uniformly stirring the raw materials to obtain the product. By adopting the technical ways of polymer modification, particle size matching optimization, component design and the like, inorganic materials are used as main materials, polymers are creatively added, and a plurality of auxiliaries are used as auxiliary materials, so that the prepared material has the advantages that the operation time is adjustable, the strength development is controllable, steel bars do not need to be planted on new and old concrete interfaces, the interface bonding performance is good, and the like; and the requirements of repairing the line skylight in time and passing the train after the skylight is lighted can be met.
本发明公开了一种高速铁路无砟道床快速更换材料，包括以下重量份的原料：胶凝材料100份、粗骨料150‑300份、细骨料100‑200份、石粉质矿物掺合料0‑30份、聚合物5‑12份、膨胀剂5‑20份、弹性增韧剂5‑10份、工作性能调节剂0.5‑2份、消泡剂0‑1份、引气剂0‑1份和水30‑200份；制备方法，具体包括以下步骤：(1)称取各原料；(2)将各原料搅拌均匀，即得。本发明通过采用聚合物改性、粒度匹配优化、组分设计等技术途径，以无机材料为主，创造性添加聚合物，辅以多种助剂，由此制得的材料具有作业时间可调、强度发展可控、新老混凝土界面无需植筋、界面粘结性能好等优点，能够满足线路天窗时间内修补、天窗点毕后列车通行的要求。
