Building muck-based bridge abutment back backfill material and preparation method and application thereof
The invention belongs to the technical field of road bridge and culvert abutment backfill materials, and discloses a construction muck-based bridge abutment backfill material and a preparation method and application thereof. The backfill material disclosed by the invention is prepared from the following raw materials in parts by mass: 1000 to 1400 parts of muck, 1500 to 2100 parts of muck-based aggregate, 163 to 180 parts of granulated blast furnace slag powder, 50 to 123 parts of electronic sludge, 38 to 53 parts of desulfurized gypsum, 45 to 63 parts of alkali activator, 12 to 18 parts of quick lime, 1.3 to 1.8 parts of water reducing agent, 8 to 12 parts of aluminum powder paste, 1.7 to 2.5 parts of sodium alpha-olefin sulfonate, 2.3 to 3.3 parts of polyacrylamide, 1 to 1.4 parts of ammonium stearate and 1250 to 1750 parts of water. The backfill material makes full use of solid wastes such as building muck and electronic sludge, has the properties of light weight, water permeability, high strength and the like, and is particularly suitable for backfill of bridge abutment backs.
本发明属于公路桥涵台背回填材料技术领域，公开了一种建筑渣土基桥梁台背回填材料及其制备方法和应用。本发明回填材料包括以下质量份数的原料：渣土1000～1400份、渣土基骨料1500～2100份、粒化高炉矿渣粉163～180份、电子污泥50～123份、脱硫石膏38～53份、碱激发剂45～63份、生石灰12～18份、减水剂1.3～1.8份、铝粉膏8～12份、α‑烯基磺酸钠1.7～2.5份、聚丙烯酰胺2.3～3.3份、硬脂酸铵1～1.4份、水1250～1750份。本发明回填材料充分利用建筑渣土、电子污泥等固废，具有轻质、透水、高强等性能，特别适用于桥梁台背回填。
