Ultrahigh-strength resin elastic concrete for bridge expansion joints and preparation method of ultrahigh-strength resin elastic concrete
The invention relates to the technical field of bridge expansion joints, and discloses ultrahigh-strength resin elastic concrete for bridge expansion joints, which comprises a component A, a component B and a component C. The component A is a main agent, the component B is a curing agent, the component C is aggregate, the main agent is graphene modified epoxy resin, and the weight ratio of the component A to the component B is (60-100): (30-60). The total weight of the component A and the component B accounts for 10-15% of the weight of the component C. The ultrahigh-strength resin elastic concrete is high in mechanical strength, track dynamic stability and interface concrete shear strength, more durable in use, capable of absorbing impact stress, free of a profile steel structure, capable of greatly shortening construction time, short in maintenance time, free of obvious bumping when a vehicle runs through an expansion joint, lower in noise and easy to maintain.
本发明涉及桥梁伸缩缝技术领域，公开了一种桥梁伸缩缝用超高强树脂弹性混凝土，包括A、B、C三组分，A组分为主剂，B组分为固化剂，C组分为骨料，主剂为石墨烯改性环氧树脂，A组分和B组分的重量比为60‑100:30‑60；A组分和B组分的总重量占C组分重量的10‑15%。超高强树脂弹性混凝土力学强度、车辙动稳定度、与界面混凝土剪切强度高，使用更耐久，能吸收冲击应力，可免除型钢结构，极大地缩短施工时间，且养护时间短，车辆行驶通过伸缩缝无明显跳车，噪音更低，易维护。
