Abstract

Provided is a mortar composition in which water is mixed with solids that comprise: 7.5 weight parts of coal ash; 1.5 to 3.0 weight parts of cement; 1.0 to 2.0 weight parts of calcined gypsum; 1.0 to 2.0 weight parts of quicklime (CaO); 0.01 to 2.0 weight parts of a retardant; and 0.01 to 0.5 weight parts of a viscosity increasing agent, to thereby prepare a mortar having high compressive strength without using sand.
