Quick-hardening high-performance hinge joint filling material
The invention discloses a quick-hardening high-performance hinge joint filling material, which is prepared from the following raw materials in parts by weight: 10 to 12 parts of Portland cement, 35 to 37 parts of aluminate cement, 1 to 2 parts of redispersible latex powder, 0.03 to 0.05 part of carbon nano tube, 1 to 1.3 parts of gypsum, 0.6 to 0.9 part of composite admixture, 49.37 to 51.2 parts of aggregate and 3 to 3.5 parts of steel fiber. The filling material takes a class-IV cement based grouting material as a base, the filling material is formed by matching materials such as the Portland cement, aluminate cement, redispersible latex powder, carbon nano tubes, gypsum, a composite additive, aggregate and steel fibers, the composite additive comprises a high-efficiency water reducing agent, a defoaming agent and a plastic expanding agent, and the steel fibers are fine steel fibers and are distributed in a disordered mode. Under the effect of the Portland cement, the aluminate cement, the redispersible latex powder, the carbon nanotubes, the gypsum, the composite admixture, the aggregate and the steel fibers, the performance requirements of the bridge reinforcing hinge joint filling material are met.
本发明公开了快硬型高性能铰缝填筑料，包括以下重量份的原料：硅酸盐水泥10‑12份、铝酸盐水泥35‑37份、可再分散乳胶粉1‑2份、碳纳米管0.03‑0.05份、石膏1‑1.3份、复合外加剂0.6‑0.9份、骨料49.37‑51.2份、钢纤维3‑3.5份，所述填筑料选用Ⅳ类水泥基灌浆料作为基础配合比，且填筑料由硅酸盐水泥、铝酸盐水泥、可再分散乳胶粉、碳纳米管、石膏、复合外加剂、骨料和钢纤维等材料配合而成，所述复合外加剂包括高效减水剂、消泡剂和塑性膨胀剂，钢纤维选用微细钢纤维，且为乱向分布。本发明通过硅酸盐水泥、铝酸盐水泥、可再分散乳胶粉、碳纳米管、石膏、复合外加剂、骨料和钢纤维的作用，满足了桥梁加固铰缝填筑材料的性能需求。
