Super-tough dry-mixed mortar and preparation method thereof
The invention relates to super-tough dry-mixed mortar and a preparation method thereof. The super-tough dry-mixed mortar comprises a component A and a component B. The component A comprises, by weight, 120-500 parts of cement, 2-10 parts of an additive and 0.01-10 parts of a polyhydroxy compound; the component B comprises, in parts by weight, 200-1200 parts of building sand and 0-600 parts of tailings; and a weight ratio of the component A to the component B is 1: (1.0-4.0). The polyhydroxy compound can significantly improve the toughness and cracking resistance of concrete, so compared with traditional dry-mixed mortar, the mortar has the functional characteristics of high toughness, abrasion resistance, high damping and the like, can be used as plastering mortar for walls, grounds and the like, and can cope with the engineering problems of large-area mortar shrinkage and cracking, high temperature in summer, scouring in rainy seasons and the like; and the use of other admixtures can be greatly reduced due to the dispersion, water reduction and delayed coagulation effects of the super-tough dry-mixed mortar at normal temperature.
本发明涉及超韧性干粉砂浆及其制备方法，所述的超韧性干粉砂浆包括A组分和B组分，所述的A组分按照重量份计，包括水泥120~500份，外加剂2~10份，多羟基化合物0.01~10份；所述的B组分按照重量份计，包括建筑用砂200~1200份，尾矿0~600份；所述的A组分与B组分的重量比为1:(1.0~4.0)。多羟基化合物可以显著提高混凝土韧性和抗开裂性能，使本发明较传统干粉砂浆具有高韧性、耐冲磨、高阻尼等功能特性，可用作墙面、地面等抹灰砂浆，可应对大面积砂浆收缩开裂、夏季高温、雨季冲刷等工程问题，常温下其具有的分散、减水、缓凝作用可大大减少其他外加剂的使用。
