Anti-crack plastering mortar
The invention belongs to the field of building mortar, and provides anti-crack plastering mortar which comprises the following components in parts by weight: 120-200 parts of ordinary cement, 2-30 parts of special cement, 0-100 parts of admixture, 0-80 parts of filler, 560-880 parts of graded sand, 0.2-0.8 part of water retention thickener, 0.1-0.5 part of polymer, 0.1-0.5 part of fiber, 0-0.5 part of water reducing agent and 0-30 parts of antifreezing agent. Hydroxyl of polyvinyl alcohol and oxygen atoms on ether bonds in cellulose ether are associated to form hydrogen bonds, so that the super-superposition effect is achieved, and an extremely small amount of polyvinyl alcohol is compounded with the cellulose ether to achieve the anti-cracking reinforcing effect; natural sand is replaced by the tailing sand, so that the problems of risks caused by accumulation of the tailing sand and shortage of building mortar raw materials are solved, and thick-layer plastering without cracking is realized; the ordinary cement and the special cement are compounded for use, so that the constructability, early strength, crack resistance and durability of the mortar are obviously improved.
本发明属于建筑砂浆领域，提供了一种抗裂抹灰砂浆，包括按重量份计的下列组分：普通水泥120～200、特种水泥2～30、掺和料0～100、填料0～80、级配砂560‑880、保水增稠剂0.2～0.8、聚合物0.1～0.5、纤维0.1～0.5、减水剂0～0.5、防冻剂0～30。本发明利用聚乙烯醇的羟基与纤维素醚中醚键上的氧原子缔合成氢键而具有的超叠加效应，使得极少量的聚乙烯醇复合纤维素醚即获得抗裂增强作用；利用尾矿砂代替天然砂，以解决尾矿砂堆积导致的风险及建筑砂浆原料匮乏问题，并实现可厚层抹灰而不开裂；将普通水泥与特种水泥复合使用，使砂浆施工性、早期强度、抗裂性、耐久性明显提升。
