Article of Lightweight Inorganic Agglomerate in Form of Slab, Process of Manufacturing the Same and Resulting Panel

Conglomerate article in sheet form, obtainable from an initial mix comprising a granular material of selected particle size, a water-based binder and a filler, said mix, after deposition on a support being subjected to vacuum pressing with simultaneous application of a vibratory movement and afterwards subjected to drying in order to remove the mix water, characterized in that:

• said granular material consists of expanded glass or ceramic material, having a particle size of between 0.1 and 12 mm and preferably 0.5 and 6 mm;
• said filler consists of hollow inorganic microspheres and a plasticizer;
• and
• said binder contains silicon.
