Phosphorus II type anhydrous gypsum-based self-leveling mortar and preparation method thereof
The invention discloses phosphorus II type anhydrous gypsum-based self-leveling mortar and a preparation method thereof, and relates to the technical field of building materials. The gypsum-based self-leveling mortar is prepared from 600 to 700 parts of phosphorus II type anhydrous gypsum, 100 to 180 parts of mineral powder, 35 to 65 parts of fly ash, 70 to 100 parts of cement, 1 to 2 parts of a water reducing agent, 0.5 to 1 part of a retarder, 0.4 to 0.6 part of a defoaming agent, 0.4 to 0.8 part of a suspension stabilizer, 8 to 12 parts of calcined aluminum potassium sulfate, 2.5 to 3.5 parts of calcined potassium sulfate, 30 to 70 parts of building gypsum, 5 to 15 parts of a calcium sulphoaluminate cementing material, 5 to 30 parts of calcium formate and 390 to 420 parts of water. The gypsum-based self-leveling mortar has the advantages of favorable flowability, high strength, favorable wear resistance, favorable water resistance, low slurry viscosity, excellent construction performance, high product quality controllability and favorable volume stability, solves the problem of resource utilization of ardealite, introduces the fly ash and mineral powder, realizes the synergistic integrated utilization of solid waste resources, and is favorable for industrial production. The high-performance gypsum-based green building material is obtained.
