Rapid road repairing material and preparation method thereof
The invention relates to the technical field of road maintenance, in particular to a rapid road repairing material and a preparation method thereof.According to the scheme, after mixed powder and water are mixed and blended, carborundum, high-elasticity putty powder, fiber material powder and an efficient hardening accelerator in the mixed repairing material are mixed, and the rapid road repairing material is obtained; by adding a powdery fiber material prepared by grinding wood fibers, rubber fibers and glass fibers and matching with high-elasticity putty powder, under mixing and blending of water, the periphery of 20-40-mesh high-hardness carborundum can be fully bonded, the pH value of the concrete can be reduced by modified iron oxide, and the concrete has the advantages of being high in strength, good in durability and good in durability. The low-alkalinity sulphoaluminate cement doped in the modified sulphoaluminate cement is matched, so that the alkalinity of the concrete can be reduced, and the concrete repair material provided by the scheme has the advantages of short setting time, good cohesiveness of the internal filler, good matching with original concrete pores of a road surface and high compressive strength after curing.
本发明涉及道路养护技术领域，尤其为一种道路快速修复材料及其制备方法，本方案的混合粉料与水混合调配后，其中混合修复材料中的金刚砂、高弹性腻子粉、纤维料粉以及高效促硬速凝剂，通过添加有木质纤维、橡胶纤维以及玻璃纤维粉磨制成的粉状纤维料，配合高弹性腻子粉，在水的混合调配下，可对20‑40目高硬度金刚砂周围进行充分粘结，改性氧化铁还可以减少混凝土的pH值，配合在改性硫铝酸盐水泥中掺杂的低碱度硫铝酸盐水泥，可降低混凝土的偏碱性，本发明方案设置的混凝土修复材料内部具有凝结时间快、内部填料粘结性好、与路面原本混凝土孔隙的匹配性好以及固化后抗压强度高的优点。
