The invention discloses a cement concrete pavement rapid repairing material and mortar and, a preparation method of the mortar, wherein the rapid repairing material comprises the raw materials in parts by mass: 50 to 70 parts of Portland cement, 10 to 20 parts of aluminate cement, 5 to 15 parts of semi-hydrated gypsum, 0.1 to 0.3 part of a defoaming agent, 0.1 to 0.3 part of a water reducing agentand 10 to 20 parts of a polymer emulsion. The rapid repairing mortar comprises the raw materials: intermediate sand, water and the cement concrete pavement rapid repairing material, wherein in partsby mass, the rapid repairing mortar comprises 120 to 140 parts of the intermediate sand, the mass ratio of water and the cement concrete pavement rapid repairing material is 0.3-0.4. The rapid repairing material can prevent poor repairing effect caused by unstable later strength of sulphoaluminate cement, can overcome the defect of brittleness of a cement-based material, also has the characteristic of quickly repairing concrete, and is stable in later strength.
本发明公开一种水泥混凝土路面快速修补材料、砂浆及制备方法，快速修补材料，其原料包括硅酸盐水泥、铝酸盐水泥、半水石膏、消泡剂、减水剂和聚合物乳液；以质量份数计，硅酸盐水泥含量为50‑70份，铝酸盐水泥含量为10‑20份，半水石膏含量为5‑15份，消泡剂含量为0.1‑0.3份，减水剂含量为0.1‑0.3份，聚合物乳液含量为10‑20份。快速修补砂浆，其原料包括中级砂、水和本发明上述水泥混凝土路面快速修补材料，以质量份数计，中级砂含量为120‑140份，水与胶凝材料的质量比为0.3‑0.4。通过本发明能够防止硫铝酸盐水泥后期强度不稳定导致的修复效果不佳，还能够解决水泥基材料质脆的缺陷，同时还具有能够快速修复混凝土的特点，且后期强度稳定。
