Cement road repairing agent as well as preparation method and application thereof
The invention provides a cement road repairing agent as well as a preparation method and application thereof, and belongs to the field of building materials. The invention provides a cement road repairing agent. The cement road repairing agent is prepared from the following components in percentage by mass: 9.5 to 10.5 percent of silicon dioxide, 5.0 to 5.5 percent of calcium sulfate, 15 to 16 percent of Portland cement, 20 to 21 percent of sulphoaluminate cement, 15.5 to 16.5 percent of iron aluminate cement, 9.5 to 10.5 percent of hydrotalcite, 19 to 20 percent of calcium carbonate, 2 to 3 percent of polyvinyl alcohol, 0.4 to 0.8 percent of redispersible latex powder and 0.04 to 0.06 percent of sodium phosphate. The cement road repairing agent provided by the invention has very strong characteristics in the aspects of corrosion resistance, crack resistance and the like, the sulphoaluminate cement has the characteristics of early strength and high strength, the 3-day strength of the sulphoaluminate cement is equivalent to the 28-day strength of Portland cement with the same grade, and the early strength of the repairing agent can be effectively improved.
本发明提供了一种水泥道路修补剂及其制备方法和应用，属于建筑材料领域。本发明提供了一种水泥道路修补剂，包括以下质量百分含量的组分：二氧化硅9.5～10.5％，硫酸钙5.0～5.5％，硅酸盐水泥15～16％，硫铝酸盐水泥20～21％，铁铝酸盐水泥15.5～16.5％，水滑石9.5～10.5％，碳酸钙19～20％，聚乙烯醇2～3％，可再分散乳胶粉0.4～0.8％和磷酸钠0.04～0.06％。本发明提供的水泥道路修补剂不论是在抗腐蚀性还是在抗裂等方面的特点都非常强，硫铝酸盐水泥具有早强、高强的特点，其3天强度相当于同标号硅酸盐水泥的28天强度，能够有效提高修补剂的早期强度。
