The present invention relates to a cementless composition based on blast furnace slag and fly ash, and to a method of manufacturing dry mortar using the same. More specifically, the present invention uses blast furnace slag and fly ash as a binder instead of cement, and calcined lime as an alkali activator. By applying gypsum and modified lime, it relates to a cementless composition having a physical property equivalent to or higher than that of general cement mortar, and a method of preparing dried mortar using the same. |
