The invention provides a fiber-reinforced white anti-crack mortar dry powder which is prepared by mixing the following raw materials in proportion: 500 grams of gypsum powder, 200 grams of white cement, 200 grams of siliceous lime powder, 50 grams of starch ether, 50 grams of polyvinyl alcohol, 10 grams of alkali-resistant fiber, 10 grams of alum, 5 grams of mineral shrinkage inhibitor and 5 grams of modifier, the main components of the modifier are a high-molecular polymer and an inorganic filler. The fiber-reinforced white anti-crack mortar dry powder can be used only by adding water on site, the problems of inaccurate metering and material waste caused by on-site batching in a traditional method are solved, and the prepared mortar not only solves the problem of cracking of common mortar due to various stresses, but also has the advantages of simple process and low cost. Meanwhile, the anti-crack mortar has the characteristics of water retention, delayed coagulation, water resistance, weather resistance, convenience in construction and the like, the bleeding amount of the anti-crack mortar is reduced, the elasticity is obviously improved, the viscosity is increased, the water retention capacity is improved, and the anti-crack performance is obviously improved.
本发明提供纤维增强白色抗裂砂浆干粉料，该纤维增强白色抗裂砂浆干粉料按如下原料按配比混配制成：500克石膏粉、200克白色水泥、200克硅石灰粉、50克淀粉醚、50克聚乙烯醇、10克耐碱纤维、10克明矾、5克矿物收缩抑制剂和5克改性剂，所述白色水泥为42.5号水泥，所述改性剂主要成分为高分子聚合物和无机填料。该纤维增强白色抗裂砂浆干粉料，只需现场加水即可使用，解决了传统方法现场配料造成的计量不准确和材料浪费的问题，配制的砂浆不仅解决了普通砂浆因各种应力造成的开裂问题；而且同时具有保水缓凝、防水耐候、施工方便等特点，该抗裂砂浆泌水量降低、弹性明显提高、粘度增加、保水能力提高，抗裂性能得到明显改善。
