PURPOSE: A manufacturing method of construction plastering mortar using activated natural minerals, such as kaolin, agalmatolite and mica, as raw materials is provided. The resultant mortar has cracking prevention, sound absorption and deodorization, and improved adhesive strength and initial strength compared with a conventional cement mortar. CONSTITUTION: The plastering mortar is manufactured by the following steps: grinding 70-80wt.% of main materials comprising kaolin, agalmatolite and mica, to 65-325mesh; grinding 20-30wt.% of aid materials sintered at 400-700deg.C to 325 or more mesh, where the aid materials comprise 70%(based on the weight ratio of aid materials) of ores such as sericite, phosphate, saponite, germanium ore, ferric oxide ore, cupric oxide ore, manganese oxide ore, and 30%(based on the weight ratio of aid materials) of synthetic resin; mixing main materials and aid materials.
