Rapid road repairing material as well as preparation method and application thereof
The invention discloses a rapid road repairing material and a preparation method and application thereof, and belongs to the technical field of road repairing materials. The rapid road repairing material is prepared from the following components in parts by weight: 28 to 34.5 parts of superfine Portland cement, 6.0 to 11.6 parts of superfine micro powder, 10.5 to 14.5 parts of sulphoaluminate cement, 27.0 to 29.3 parts of coarse sand, 16.5 to 18.9 parts of fine sand, 0.01 to 0.05 part of cellulose ether, 0.07 to 0.15 part of an expanding agent, 0.20 to 0.25 part of a water reducing agent, 0.08 to 0.12 part of a retarder, 0.02 to 0.06 part of lithium carbonate, 0.10 to 0.15 part of a de-foaming agent and 0.49 to 0.92 part of redispersible latex powder. The rapid road repairing material has the characteristics of early strength, crack resistance, impact resistance, self-leveling, rapid curing at normal temperature and good cohesiveness with original concrete, the compressive strength reaches 30 MPa or above within 4 hours, and traffic can be opened after the road surface is repaired for 4 hours; and the 28-day compressive strength reaches 60 MPa or above.
一种道路快速修补材料及其制备方法和应用，属于道路修补材料技术领域。所述道路快速修补材料，以重量份数计，包含以下组分：超细硅酸盐水泥28~34.5份，超细微粉6.0~11.6份，硫铝酸盐水泥10.5~14.5份，粗砂27.0~29.3份，细砂16.5~18.9份，纤维素醚0.01~0.05份，膨胀剂0.07~0.15份，减水剂0.20~0.25份，缓凝剂0.08~0.12份，碳酸锂0.02~0.06份，消泡剂0.10~0.15份，可再分散乳胶粉0.49~0.92份。本发明所述的道路快速修补材料具有早强、抗裂、耐冲击、自流平、常温下快速固化并且与原混凝土粘结性好的特点，4小时抗压强度达到30MPa以上，路面修补4小时便能开放交通；28天抗压强度达到60MPa以上。
