NOVELTY - Preparation of plastering mortar involves mixing nanosilica, silane coupling agent and molten epoxy resin to obtain a mixture, drying mixture, grinding to obtain powdery substance, mixing the obtained powdery substance with straw, cellulose ether, sodium carboxymethylcellulose, graphene oxide and N-methylpyrrolidone in presence of solvent, drying, and mixing the resultant material with polyvinyl alcohol, methyl methacrylate, cement, fine aggregates, coarse aggregates and water. USE - Preparation of plastering mortar (claimed). ADVANTAGE - The method provides plastering mortar having excellent crack resistance. DETAILED DESCRIPTION - Preparation of plastering mortar involves mixing 5-15 pts. wt. nanosilica, 1-5 pts. wt. silane coupling agent and 100 pts. wt. molten epoxy resin to obtain a mixture, drying mixture, grinding to obtain powdery substance, mixing the obtained powdery substance with 5-15 pts. wt. straw, 3-10 pts. wt. cellulose ether, 5-10 pts. wt. sodium carboxymethylcellulose, 10-30 pts. wt. graphene oxide and 1-5 pts. wt. N-methylpyrrolidone in presence of solvent, drying, and mixing the 5-15 pts. wt. resultant material with 5-15 pts. wt. polyvinyl alcohol, 5-20 pts. wt. methyl methacrylate, 30-50 pts. wt. fine aggregates, 50-60 pts. wt. coarse aggregates, 30-80 pts. wt. water and 100 pts. wt. cement.
