Plate-type ballastless track concrete based on saltpetering inhibition and mechanical properties and preparation method of plate-type ballastless track concrete
The invention discloses plate-type ballastless track concrete based on saltpetering inhibition and mechanical properties. The plate-type ballastless track concrete is prepared from the following raw materials in parts by weight: 40-45 parts of Portland cement, 15-20 parts of aggregate, 5-20 parts of fly ash, 10-15 parts of a nano silicon dioxide coordinated whisker adjusting modifier, 3-6 parts of a sodium silicate pre-adjusted chitosan solution modified bentonite body, 2-6 parts of a water reducing agent, 0.5-1 part of a retarder and 50-60 parts of deionized water. According to the plate-type ballastless track concrete, the Portland cement, the aggregate and the fly ash are matched to serve as a base material, the nano-silicon dioxide is added to coordinate with the whisker adjusting modifier and the sodium silicate pre-adjusting chitosan solution modified bentonite to be matched, the nano-silicon dioxide and the sodium silicate pre-adjusting chitosan solution modified bentonite are coordinated and jointly synergized, and the saltpetering inhibiting effect and the mechanical property effect of the product are enhanced.
本发明公开了一种基于泛碱抑制与力学性能的板式无砟轨道混凝土，包括以下重量份原料：硅酸盐水泥40～45份、骨料15～20份、粉煤灰5～20份、纳米二氧化硅协调晶须调节改性剂10～15份、硅酸钠预调壳聚糖溶液改性膨润土体3～6份、减水剂2～6份、缓凝剂0.5～1份、去离子水50～60份。本发明板式无砟轨道混凝土采用硅酸盐水泥、骨料、粉煤灰配合作为基体料，通过加入纳米二氧化硅协调晶须调节改性剂、硅酸钠预调壳聚糖溶液改性膨润土体配合，二者协调，共同协效，增强产品抑制泛碱效果以及产品的力学性能效果。
