Phosphorus II type anhydrous gypsum-based self-leveling mortar
The invention belongs to the technical field of building materials, and particularly relates to phosphorus II type anhydrous gypsum-based self-leveling mortar. The self-leveling mortar comprises water, cement, slag, an activating agent, phosphorus II type anhydrite and a water reducing agent, wherein the water reducing agent is a sulfonated melamine water reducing agent. The invention solves the technical problem that the compatibility of the existing water reducing agent and activating agent is poor when the phosphorus II type anhydrite is used for the self-leveling mortar.
本发明属于建筑材料技术领域，具体涉及一种磷II型无水石膏基自流平砂浆。所述自流平砂浆包括水、水泥、矿渣、激活剂、磷II型无水石膏和减水剂，所述减水剂为磺化三聚氢胺系减水剂。本发明解决了磷II型无水石膏用于自流平砂浆时，现有的减水剂与激活剂的相容性不佳的技术问题。
