Quick-hardening high-performance bridge deck pavement material
The invention discloses a quick-hardening high-performance bridge deck pavement material, which relates to the technical field of quick repair of bridge deck damage, and is prepared from the following raw materials in parts by weight: 28 to 30 parts of aluminum hydrochloric acid cement, 4 to 6 parts of gypsum, 0.8 to 1.1 parts of redispersible latex powder, 0.05 to 0.07 part of thickening time control agent, 2 to 3 parts of strength accelerator, 0.8 to 1.1 parts of composite additive, 62.3 to 65 parts of aggregate and 2 to 2.5 parts of steel fiber. The pavement material selects a class IV cement-based grouting material as a basic mix proportion, and is formed by matching the aluminate cement, gypsum, redispersible latex powder, a thickening time control agent, a strength accelerator, a composite admixture, aggregate, steel fiber and other materials, the composite admixture 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 manner. Under the effect of the aluminate cement, the gypsum, the redispersible latex powder, the thickening time control agent, the strength accelerator, the composite admixture, the aggregate and the steel fiber, the performance requirements of rapid repair pavement of bridge deck damage are met.
本发明公开了快硬型高性能桥面铺装材料，涉及桥面破损的快速抢修技术领域，包括以下重量份的原料：铝盐酸水泥28‑30份、石膏4‑6份、可再分散乳胶粉0.8‑1.1份、调凝剂0.05‑0.07份、促强剂2‑3份、复合添加剂0.8‑1.1份、骨料62.3‑65份、钢纤维2‑2.5份，所述铺装材料选用Ⅳ类水泥基灌浆料作为基础配合比，且铺装材料由铝酸盐水泥、石膏、可再分散乳胶粉、调凝剂、促强剂、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，所述钢纤维选用微细钢纤维，且为乱向分布。本发明通过铝酸盐水泥、石膏、可再分散乳胶粉、调凝剂、促强剂、复合外加剂、骨料和钢纤维的作用，满足了桥面破损快速抢修铺装的性能需求。
