PURPOSE: A composition for forming sheets with a surface, like rock, tree bark and soil is provided, which has flexibility, hot water resistance, and no efflorescence by using latent hydraulic inorganic powder, hydraulic cement and aqueous resin emulsion. CONSTITUTION: The sheet-forming composition comprises the components of: 100pts.wt. of basic materials containing 50-93pts.wt. of latent hydraulic inorganic powder such as blast furnace slag, and 7-50pts.wt. of hydraulic cement such as Portland cement, early-strength cement and silica cement; 0-50pts.wt. of pozzolanic inorganic powder such as fly ash, silica hume and rice hull ash; 0-300pts.wt. of non-pozzolanic inorganic powder such as CaCO3, silica, talc and pigment; 0.5-5.0pts.wt. of hydration-retardant such as sodium gluconic acid and sodium oxalic acid, and 40-100pts.wt. of aqueous resin emulsion(solid resin) such as vinyl acetate and ethyl acrylate.
