Zusammenfassung:	PURPOSE: A composition for pastering an ondol floor is provided to allow environment-friendlyness, an excellent workability at the construction, and excellent compressive strength and resistance against shrinkage deformation after the construction by mixing a dry mortar composition using industrial byproducts and a constructability enhancer. CONSTITUTION: A composition for plastering an ondol floor is a mixture of a dry mortar composition and a constructability enhancer. The dry mortar composition is formed of a blast furnace slag micropowder, cogeneration fly ash, incinerated paper mill sludge ash, gypsum, and sand. The dry mortar composition includes 3.0 to 15.0wt% of the blast furnace slag micropowder, 10.0 to 40.0wt% of the cogeneration fly ash, 3.0 to 10.0wt% of the incinerated paper mill sludge ash, 0.5 to 2.5wt% of the gypsum, and 50.0 to 80.0wt% of the sand. 0.05 to 0.15wt% of the constructability enhancer based on a weight of the dry mortar composition is mixed. The constructability enhancer comprises 70.0 to 90.0 wt% of superplasticizer and 10.0 to 30.0wt% of a retarder. The superplasticizer is at least one of a polycarboxylic acid based superplasticizer, a naphthalyene based superplasticizer, a lignin based superplasticizer, and a melamine based superplasticizer. The retarder is at least one of a boron retarder and a phosphoric acid retarder.
