<p>A water-permeable concrete formwork of thermo-plastic resin characterized in that a thermoplastic resin layer having water permeability is provided on at least one of the surfaces of a basic thermoplastic resin layer, whereby removal of moisture from placed concrete is promoted by absorption and/or permeation of moisture of said concrete by and/or through said water-permeable thermoplastic resin layer, thereby making it possible to significantly reduce the curing time of concrete.</p> |
