Gypsum self-leveling mortar
The invention belongs to the technical field of decorative mortar, and particularly relates to gypsum self-leveling mortar, which is prepared from the following raw materials: desulfurized gypsum powder, fly ash, cement, a composite air-entraining water-reducing agent, a water repellent, an expanding agent, a water-retaining agent and a toughening agent. After hydration, the crystal structure is compact, and the compressive strength of the mortar taking the desulfurized gypsum as a base material is improved after molding; a small amount of fly ash and cement are used as base materials to replace part of desulfurized gypsum powder, so that the components of the base materials are diversified, the defects of gypsum can be overcome, and the water resistance and strength of the formed mortar are improved; the composite air-entraining and water-reducing agent composed of the rosin resin air-entraining agent and the polycarboxylic acid water-reducing agent is introduced into the mortar, mortar gaps are further refined, the overall water-retaining property of the mortar is improved, the water consumption is reduced, and the water resistance and the strength of the formed mortar are further improved.
本发明属于装饰砂浆技术领域，具体涉及一种石膏自流平砂浆，其原材料组成包括：脱硫石膏粉、粉煤灰、水泥、复合引气减水剂、憎水剂、膨胀剂、保水剂、增韧剂，以脱硫石膏粉为基材，脱硫石膏粉与普通天然石膏粉相比，无放射性，水化后结晶结构紧密，以脱硫石膏为基材的砂浆，成型后抗压强度得到提升；以少量的粉煤灰和水泥为基材代替部分脱硫石膏粉，使得基材成分多元化，可弥补石膏自身的不足，使得砂浆成型后的耐水性、强度均有所提升；在砂浆中引入由松香树脂引气剂和聚羧酸减水剂组成的复合引气减水剂，进一步细化砂浆空隙，且增加砂浆整体的保水性，减少水的用量，是砂浆成型后的耐水性和强度进一步得到改善。
