High-performance hinge joint filling material
The invention discloses a high-performance hinge joint filling material, and relates to the technical field of bridge reinforcement or reconstruction in civil engineering. The high-performance hinge joint filling material comprises the following raw materials by weight: 40-45 parts of Portland cement, 5-7 parts of aluminate cement, 1-1.3 parts of redispersible latex powder, 0.05-0.08 part of carbon nanotubes, 2-2.5 parts of an expanding agent, 0.4-0.6 part of a composite admixture, 48.55-50 parts of aggregate, and 3-4.3 parts of steel fiber. The hinge joint filling material is formed by matching materials such as Portland cement, aluminate cement, redispersible latex powder, carbon nanotubes, an expanding agent, a composite additive, aggregate and steel fibers, wherein the composite additive comprises a high-efficiency water reducing agent, a defoaming agent and a plastic expanding agent. Under the effect of the Portland cement, the aluminate cement, the redispersible latex powder, the carbon nanotubes, the expanding agent, the composite admixture, the aggregate and the steel fibers, the high-strength and high-toughness concrete has good construction performance, high strength and high toughness, and does not need middle-end traffic.
本发明公开了高性能铰缝填筑料，涉及土木工程中的桥梁加固或改建技术领域，包括以下重量份的原料：所述硅酸盐水泥40‑45份、铝酸盐水泥5‑7份、可再分散乳胶粉1‑1.3份、碳纳米管0.05‑0.08份、膨胀剂2‑2.5份、复合外加剂0.4‑0.6份、骨料48.55‑50份、钢纤维3‑4.3份，所述铰缝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、膨胀剂、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。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、膨胀剂、复合外加剂、骨料和钢纤维的作用，使其具有良好的施工性能和高强度以及高韧性，且无需中端交通的能力。
