Super-early-strength shrinkage compensation road and bridge rapid repair material and preparation method thereof
The invention discloses a super-early-strength shrinkage compensation road and bridge rapid repair material and a preparation method thereof. The repair material comprises the following components: ordinary Portland cement, quick-hardening cement, a shrinkage compensation material, an active admixture, graded high-quality quartz sand with fineness modulus of 2.0-3.2, aggregate, a water reducing agent, a setting rate regulator, an early strength agent, fibers, a maintenance-free agent and a surfactant. The material can be used by adding water according to a recommended water-binder ratio and uniformly stirring, the uniformity and consistency of the material are good, the initial setting time is 35-45 minutes, the final setting time is 50 minutes, maintenance is not needed after pouring is finished, and traffic can be opened after 1.0-4.0 hours. The rapid repair material has the advantages of being good in construction workability, simple and convenient in on-site construction process, high in material strength increase speed, resistant to pressure, fracture and elasticity modulus, high in bonding strength with an existing structure and the like. The rapid repair material is suitablefor rapid repair, maintenance and reinforcement of engineering structures such as municipal roads and bridges, high-speed roads and bridges, high-speed railway bridges and various tunnels.
本发明公开了一种超早强收缩补偿道桥快速修复材料及其制备方法，所述修复材料包括如下组分：普通硅酸盐水泥，快硬水泥，补偿收缩料，活性掺合料，细度模数为2.0~3.2的级配高质石英砂，骨料，减水剂，凝速调节剂，早强剂，纤维，免养护剂，表面活性剂。所述材料按照推荐水胶比加水搅拌均匀即可使用，并且材料的均匀性和一致性良好，初凝时间为35~45分钟，终凝50分钟，浇筑完毕后无需养护，1.0~4.0小时即可开放交通。本发明的超早强收缩补偿道桥快速修复材料具有施工和易性好、现场施工工艺简便，材料强度上升快，抗压、抗折、弹性模量以及与既有结构粘结强度高等优点。本发明适用于市政路桥、高速路桥、高铁路桥以及各类隧道等工程结构的快速修复和维护加固。
