Method for manufacturing cladding elements for use in construction

A method for manufacturing cladding elements for use in construction comprising a composite cement-based structure, said method comprising:

• providing an elastically deformable support element, comprising a first surface and a second surface defining a volume within which a plurality of spacer elements, having an elongated shape, connects the first and second surface and are arranged so as to realize a plurality of interconnected cavities within said volume;
• preparing a substantially fluid water-based cementitious composition;
• introduce said substantially fluid cementitious composition into the support element so as to obtain a deformable composite structure in a deformable state;
• removing part of the fluid cementitious composition from the support element, to remove the excess fluid cementitious composition;
• positioning said deformable composite structure in a forming device;
• maintaining said deformable composite structure in association with the forming device, until solidification of thereof;
• wherein
• said support element is constituted by a three-dimensional elastically deformable fabric;
• and wherein
• said cementitious composition comprises at least one fluidifying and/or plasticizing additive and in which cement, additive and water are present according to a weight ratio variable from 1:
• 1/3;
• 1/3 to 1;
• 1/6;
• 1/6.
