Repair material for ballastless track bed concrete defects
The present invention relates to the technical field of engineering materials, and discloses a ballastless track bed concrete defect repairing material, which comprises the following raw materials by weight: 15 parts of a cement quartz sand silica fume fly ash floating bead redispersible latex powder water-retaining agent, a desulfurization gypsum water-reducing agent, and 2 parts of an early strength agent fiber material modified dispersion thixotropic agent curing agent. The repairing material for the concrete defects of the ballastless track bed is a polymer modified cement-based composite material, the advantages that an inorganic material is easy to obtain, good in durability, environmentally friendly and low in price are played, the advantage of high flexibility of a polymer is highlighted, and the repairing material can be used for repairing the concrete defects of the ballastless track bed. And the concrete repairing agent is specially used for rapidly repairing the concrete defects of the ballastless track bed of the high-speed railway.
本发明涉及工程材料技术领域，且公开了一种用于无砟轨道床混凝土缺损的修补材料，包括以下重量份数配比的原料：水泥石英砂硅灰粉煤灰漂珠可再分散乳胶粉保水剂脱硫石膏减水剂15份，早强剂纤维材料改性分散触变剂养护剂2份。该用于无砟轨道床混凝土缺损的修补材料，这种无砟轨道床混凝土缺损修补材料，是一种聚合物改性的水泥基复合材料，发挥了无机材料易得、耐久性好、环境友好，价格想对便宜的优点，又突出了聚合物高柔韧性的优势，加水搅拌均匀即可使用，专用于高速铁路无砟轨道床混凝土缺损伤的快速修复。
