Plastering mortar as well as preparation method and application thereof
The invention discloses plastering mortar as well as a preparation method and application thereof. The plastering mortar comprises the following components in parts by weight: 60-100 parts of shield muck; 20 to 50 parts of cement; 5 to 40 parts of graded sand; 3-10 parts of quick lime; 1 to 10 parts of redispersible latex powder; 0.1 to 1 part of fiber; the invention relates to a high-strength concrete, which comprises the following components in parts by weight: 0.1-0.5 part of a polymethyl methacrylate-methacrylic acid copolymer, 0.1-0.5 part of an organic silicon water repellent and 0.5-3 parts of a compound water reducing agent, and the compound water reducing agent is a mixture formed by one or more of sodium hexametaphosphate, sodium tripolyphosphate, sodium pyrophosphate, sodium carbonate, sodium phosphate and sodium oxalate. According to the plastering mortar, the compound water reducing agent is added, so that the problems that the shield muck is high in viscosity and difficult to stir uniformly are effectively solved, and the obtained plastering mortar has good working performance and decorative effect and has the functions of heat preservation, heat insulation and indoor humidity adjustment.
本发明公开了一种抹灰砂浆及其制备方法与应用，所述抹灰砂浆包括以下重量份的组分：盾构渣土60～100份；水泥20～50份；级配砂5～40份；生石灰3～10份；可再分散性乳胶粉1～10份；纤维0.1～1份；有机硅憎水剂0.1～0.5份，以及复配减水剂0.5～3份，其中，所述复配减水剂包括聚甲基丙烯酸甲酯‑甲基丙烯酸共聚物与六偏磷酸钠、三聚磷酸钠、焦磷酸钠、碳酸钠、磷酸钠和草酸钠中的一种或多种形成的混合物。上述抹灰砂浆通过添加复配减水剂，有效解决了盾构渣土黏性大、难以搅拌均匀的问题，使获得的抹灰砂浆具有良好的工作性能和装饰效果，并具有保温隔热、调节室内湿度功能。
