Rapid repairing material for cement concrete pavement and preparation method of rapid repairing material
The invention provides a cement concrete pavement rapid repairing material and a preparation method thereof, the repairing material is a ferronickel slag gelling material, and the material comprises the following components in parts by weight: 100 parts of ferronickel slag, 70 parts of hydrochloric acid, 97-146 parts of light-burned magnesia powder, 27-54 parts of water, 20-30 parts of citric acid, and 20-30 parts of polyvinyl alcohol fiber, and the ferronickel slag gelling material is prepared from the following components in parts by weight: 100 parts of ferronickel slag, 70 parts of hydrochloric acid, 97-146 parts of light-burned magnesia powder and 27-54 parts of water. The citric acid accounts for 0.5%-1.5% of the mixing amount of the caustic-burned magnesia powder, and the polyvinyl alcohol fiber accounts for 0.5%-1.5% of the mixing amount of the caustic-burned magnesia powder by volume. The material has the characteristics of quick hardening, early strength, high bonding strength, small shrinkage, good working performance, simple construction process, good impact resistance, good wear resistance and the like, and has the advantages of being capable of realizing quick repair of cement concrete, good in long-term performance and the like.
本发明提供了一种水泥混凝土路面快速修补材料及制备方法，修补材料为镍铁渣胶凝材，该材料包括以下组分：镍铁渣、盐酸、轻烧镁粉、水、柠檬酸、聚乙烯醇纤维，其中，以重量份数计量，镍铁渣100份，盐酸70份，轻烧镁粉97‑146份，水27‑54份，柠檬酸为轻烧镁粉掺量的0.5％‑1.5％，聚乙烯醇纤维体积掺量0.5％‑1.5％，本发明材料具有快硬早强、粘结强度高、收缩小、工作性能好、施工工艺简单、抗冲击性能好、耐磨性好等特点，能够实现水泥混凝土的快速修复且长期性能好等优点。
