Phosphogypsum-based fireproof plastering mortar for steel tube bundle shear wall
The invention belongs to the field of house building materials, and discloses phosphogypsum-based fireproof plastering mortar for a steel tube bundle shear wall, which comprises an ardealite cementing material, a lightweight aggregate and an additive in a mass ratio of 85 to 90: 10 to 15: 1 to 2.3. According to the technical scheme, the semi-hydrated gypsum produced from industrial waste phosphogypsum is used as a main cementing material, and the mixing amount is greater than 85%, so that a large amount of solid waste phosphogypsum is effectively utilized; the product has double functions of fireproof coating and plastering mortar, and fire prevention and decoration of the steel structure shear wall are completed together after construction.
本发明属于房屋建筑材料领域，公开了一种钢管束剪力墙的磷石膏基防火抹面砂浆，包括磷石膏胶凝材料、轻骨料及外加剂，所述磷石膏胶凝材料、轻骨料与外加剂的质量比为85～90:10～15:1～2.3。本发明通过上述技术方案，以工业废弃物磷石膏生产的半水石膏作为主要胶凝材料且掺量大于85％，使大宗固体废弃物磷石膏得到有效利用；产品具备防火涂料和抹灰砂浆双重功能，在施工后对钢结构剪力墙的防火和装饰一并完成。
