Quick repair mortar for horizontal surface defects and preparation method of quick repair mortar
The invention relates to the technical field of building materials, and particularly discloses quick repair mortar for horizontal surface defects and a preparation method thereof. The quick repair mortar is prepared from the following raw material components in parts by mass: 90 to 100 parts of quick-hardening sulphoaluminate cement clinker, 100 to 120 parts of natural sand, 4 to 8 parts of gypsum, 5 to 15 parts of a polyacrylate-polyurethane copolymer emulsion, 1 to 2.5 parts of a hardening accelerator, 0.08 to 0.3 part of a retarder, 0.5 to 1 part of a water reducing agent, 0.1 to 0.2 part of an antifoaming agent, and 20 to 30 parts of water. The quick repair mortar provided by the invention has the advantages of lower dry shrinkage rate and expansion rate, higher early strength, favorable impact toughness, favorable impermeability, favorable freeze-thaw resistance and favorable bonding durability, and can achieve favorable concrete repair effect.
本发明涉及建筑材料技术领域，具体公开一种用于水平表面缺陷的快速修补砂浆及其制备方法。所述快速修补砂浆包括如下质量份数的原料组分：快硬硫铝酸盐水泥熟料90‑100份；天然砂100‑120份；石膏4‑8份；聚丙烯酸酯‑聚氨酯共聚乳液5‑15份；促硬剂1‑2.5份；缓凝剂0.08‑0.3份；减水剂0.5‑1份；消泡剂0.1‑0.2份和水20‑30份。本发明提供的快速修补砂浆具有较小的干缩率和膨胀率，较高的早期强度、良好的抗冲击韧性、抗渗性、抗冻融性和粘结耐久性，能够达到良好的混凝土修补效果。
