Polymer modified high-adhesion super-early-strength composite material
The invention discloses a polymer modified high-viscosity super-early-strength composite material, which is prepared from the following raw materials in parts by mass: 300 to 550 parts of composite high-strength cement, 50 to 200 parts of active mineral admixture, 30 to 100 parts of multi-source composite expanding agent, 400 to 750 parts of fine aggregate, 1 to 3 parts of water reducing agent, 0.5 to 4.5 parts of retarder and 2 to 5 parts of polymer modifier. The polymer modified high-bonding super-early-strength composite material prepared by the method has the characteristics of super early strength, high bonding strength and high crack resistance, and the defects that a common early-strength repair material is easy to shrink and crack, poor in bonding performance with an existing structure and the like are remarkably improved. The invention is suitable for the field of rapid repair and maintenance of various bridge expansion joints, pavement defects, airport runways and the like, has the advantages of rapid early strength rise, rapid traffic opening, high bonding strength with the existing structure, guarantee of cooperative stress of new and old parts, and substantial improvement of the durability and safe operation life of the structure to be constructed.
本发明公开了一种聚合物改性高粘结超早强复合材料，包括如下质量份数的原料：复合高强水泥300‑550份，活性矿物掺合料50‑200份，多源复合膨胀剂30‑100份，细集料400‑750份，减水剂1‑3份，缓凝剂0.5‑4.5份，聚合物改性剂2‑5份。本发明制备的聚合物改性高粘结超早强复合材料，具有超早强、高粘结强度和高抗裂性能的特点，显著改善普通早强修复材料易收缩开裂、与既有结构粘结性能差等缺点。本发明适用于各类桥梁伸缩缝、路面缺陷、机场跑道等的快速修复和维护领域，早期强度上升快，可快速开放交通，与既有结构粘结强度高，保证了新旧部分协同受力，大幅提高待结构的耐久性和安全运营寿命。
