PURPOSE: A polymer cement-based adhesive for adhering wooden ondol floors to the under plates is provided to prevent the generation of harmful gas, keep adhesiveness lastly and improve workability unlike conventional epoxy-based adhesive. CONSTITUTION: The polymer cement-based adhesive comprises 20-50wt.% of Portland cement, 5-30wt.% of alumina cement, 0.05-0.5wt.% of fluidifying agent, 0.02-5wt.% of antifoaming agent, 0.05-5wt.% of tartaric acid-based retardant, 0.05-0.5wt.% of lithium carbonite-based hardening promoter, 4-10wt.% of slaked lime, 0.5-10wt.% of gypsum, 3-30wt.% of powdered resin such as ethylene vinyl acetate(EVA) or acrylic resin, 0.01-5wt.% of polysaccharide-based repairing agent, and 13-25wt.% of water.
