    • 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.

    • PURPOSE: An environment-friendly binding material composition for a concrete is provided to reduce a weakening of the durability, and the intensity of the concrete due to the use of large amount of industrial byproduct and reduced amount of cement by adding a high-calcium ash and an activator in a pulverized ground granulated blast furnace slag and a fly ash which are the main raw material to the specified range. CONSTITUTION: An environment-friendly binding material composition for a concrete comprises 5-20wt% of cement; 30-70wt% of pulverized ground granulated blast furnace slag; 5-15wt% of high calcium ash; 10-30wt% of fly ash; 3-7wt% of activation binding material. The activation binding material comprises more than one among gypsum dihydrate, and anhydrous gypsum and a calcium sulfate. The high calcium ash contains 20-60wt% of free lime (CaO), and 2-7wt% of SO3; and has the fineness of 2,000-5,000 cm^2/g. The pulverized ground granulated blast-furnace slag which is fine pulverized ground granulated blast furnace slag has the fineness of 3,000-4,500 cm^2/g. The cement, the ground granulated blast furnace slag, the high calcium ash, the activation binding material of the binder composition contains SO3. The content of the free lime about the whole binder composition is 1-8wt%, and the content of SO3 about the whole binder composition is 4-8wt%. [Reference numerals] (AA) Temperature (°C)
