NOVELTY - Dry-mix plastering mortar includes 150-190 pts. wt. cement, 10-30 pts. wt. fly ash, 100-140 pts. wt. coarse sand, 370-390 pts. wt. fine sand, 280-320 pts. wt. river sand and 10-20 pts. wt. admixture. The admixture includes 10-20 pts. wt. silicon carbide, 5-10 pts. wt. graphene, 10-20 pts. wt. modified starch ether, 5-10 pts. wt. polypropylene fiber, 10-15 pts. wt. fatty acid salt, 10-20 pts. wt. styrene and butadiene copolymer rubber powder and 30-40 pts. wt. 90-95% ethanol. USE - Dry-mix plastering mortar. ADVANTAGE - The dry-mix plastering mortar has the advantages of high bonding strength and good thermal conductivity, and the preparation method has the advantages of simple steps, strong operability, high adhesive strength and good thermal conductivity of the prepared dry-mix plastering mortar. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing dry-mix plastering mortar, which involves drying the river sand until the water content is less than 0.5 wt.%, then mixing the river sand, cement, fly ash, gypsum, machine coarse sand and machine fine sand uniformly, and baking at 30-40 degrees C for 60-70 minutes, grinding for 10-20 minutes, and finally adding air-entraining agent, water-reducing agent and admixture, mixing uniformly, and then obtaining dry mixing plaster mortar.
