Beschreibung
Zusammenfassung:	The invention discloses a plastering premixed dry mortar comprising the following raw materials by weight: 11-25 parts of 32.5 complex portland cement, 69-83 parts of dry sand, 5-8 parts of coal ash, 0.07 part of hydro soluble cellulose ether, 1.2 parts of black talc, 0.04 part of calcium formate powder, and 0-0.04 part of triterpenoid saponins powder. The plastering premixed dry mortar has the technical effects that the raw materials of mortar are premixed to form the premixed dry mortar, in this way, the stirring time of the raw materials of mortar is reduced, and the construction efficiency is enhanced.
