The invention relates to the technical field of concrete ground repairing materials, in particular to a rapid repairing agent for a high-freeze-thaw-resistant concrete pavement. Comprising the following raw materials in parts by weight: 350-450 parts of quick-setting and quick-hardening high belite sulphoaluminate cement, 50-150 parts of Portland cement, 0-30 parts of silica fume, 45-600 parts of river sand, 0-5 parts of a cement plasticizer, 0.3-5 parts of a defoaming agent, 1-5 parts of a retarder, 1-10 parts of a coagulant, 5-35 parts of a crystallizing agent, 1.5-10 parts of a nano nucleating agent and 15-60 parts of a binder. The compactness and crack resistance of the repairing material are improved; meanwhile, the coagulant and the nano nucleating agent are added, so that the early strength of the cement repairing material can be remarkably improved, the initial setting time of the cement repairing material is shortened, and the early compressive strength of mortar is improved, so that rapid repairing of a concrete pavement is realized, and compared with base concrete which is high in bonding strength, low in shrinkage and high in impermeability, and the freeze-thaw resistance is doubled compared with the standard requirement of the freeze-thaw resistance.
本发明涉及混凝土地面修补材料技术领域，特别涉及一种高抗冻融混凝土路面快速修补剂；包括以下重量份的原料：快凝快硬高贝利特硫铝酸盐水泥350‑450份、硅酸盐水泥50‑150份、硅灰0‑30份、河沙45‑‑600份、水泥塑化剂0‑5份、消泡剂0.3‑5份、缓凝剂1‑‑5份、促凝剂1‑10份、结晶剂5‑35份、纳米成核剂1.5‑10份、粘结剂15‑60份；本发明提高了修补材料的密实性、抗裂性能；同时添加促凝剂和纳米成核剂，可以显著提水泥修补料的早强性能，加快水泥修补料初凝时间，提高砂浆早期抗压强度，从而实现混凝土路面的快速修补，比基层混凝土粘结强度高，低收缩，高抗渗，较抗冻融性能标准要求提高了一倍。
