Water-resistant lightweight gypsum mortar
The invention discloses water-resistant lightweight gypsum mortar, and relates to the technical field of building materials. A large number of glass beads and other aggregates/fillers need to be consumed in traditional light plastering gypsum production, and the glass beads obviously belong to high-energy-consumption products and do not conform to the light plastering gypsum in green and low-carbon performance. According to the invention, the waste material generated in the production process of the mixed-phase gypsum is crushed and screened to replace the vitrified micro bubbles in the existing light plastering gypsum, so that the cost is lower. The thixotropic lubricant is introduced to improve the constructability of the light plastering gypsum, so that the addition amount of the mixed-phase gypsum can be greatly increased, and the obtained light plastering gypsum has the characteristics of high strength, strong binding power and good constructability. Through comprehensive design of various measures, the performance indexes of the lightweight plastering gypsum prepared from a large amount of aerated concrete meet the requirements of GB/T 28627-2012 Plastering Gypsum.
本发明公开了一种耐水轻质石膏砂浆，涉及建筑材料技术领域。传统轻质抹灰石膏生产中需消耗大量玻化微珠及其他骨料/填料，玻化微珠明显属于高能耗产品，与轻质抹灰石膏绿色、低碳性能不符。本发明采用混合相石膏生产过程中产生的废料，经破碎、筛分后替代现有轻质抹灰石膏中的玻化微珠，因此具有较低的成本。本发明引入触变润滑剂改善轻质抹灰石膏施工性，从而可以大幅提高混合相石膏的添加量，本发明得到的轻质抹灰石膏具有强度高、粘结力强、施工性好的特点。且通过多种措施综合设计，本发明以大量加气混凝土制备得到的轻质抹灰石膏性能指标均满足GB/T 28627‑2012《抹灰石膏》要求。
