Abstract: A method for making an accessory cladding element for use in architecture and design. The method provides preparing an elastically deformable support element, including a first outer surface, in particular a decorated surface, a second outer surface and a plurality of spacer elements placed between the two surfaces. An impermeable and removable layer is applied on the first outer surface to protect at least a part thereof. Then a fluid cement mixture is prepared and introduced into the support element to obtain a cement-based composite structure in a deformable state. The excess fluid cement mixture is removed from the support element. The cement-based composite structure in the deformable state is positioned in a forming device which gives it the desired shape. The composite structure is solidified and after the removable layer is removed.

Abstract: A method for manufacturing cladding elements for use in construction, including a composite cement-based structure, including an elastically deformable support element having a first surface, a second surface and a plurality of spacer elements having an elongated shape positioned between the first and second surface to realize a plurality of interconnected cavities. The method further provides preparing a substantially fluid and water-based cementitious composition and introducing the substantially fluid cementitious composition into the support element to obtain a composite structure in a deformable state. After this, part of the fluid cementitious composition is removed from the support element, to eliminate the excess fluid cementitious composition and position the deformable composite structure in a forming device.
