Sandwich wall construction formed of spaced-apart slabs with insulation in-between having a high carbon content

A load-bearing wall element for buildings, the load-bearing wall element having an upper end, a lower end, a first side and a second side opposite the first side, comprising:

• a first support plate and a second support plate spaced apart from the first support plate to form two symmetrically arranged support plates, wherein each support plate is made of at least one of natural stone, artificial stone, ceramic, concrete, glass, or glass-containing material;
• a first fiber-containing matrix layer on an inner side of the first support plate,
• a second fiber-containing matrix layer on an inner side of the second support plate,
• wherein each fiber-containing matrix layer includes carbon fibers, and at least one of epoxy resin, polyester resin, phenolic resin, polyamide resin, cyanate ester resin, melamine resin, polyurethane resin, silicone resin, silicate resin, ceramic, or water glass;
• a first load introduction intake structure positioned at the upper end of the wall, disposed between and bonded to the first and second fiber-containing matrix layers via permanent, shear-resistant adhesives,
• a second load introduction intake structure positioned at the lower end of the wall, disposed between and bonded to the first and second fiber-containing matrix layers via permanent, shear-resistant adhesives;
• a shear-resistant layer made of a carbon-containing insulation material including a cement binder and carbon in powder form,
• wherein the shear-resistant layer comprises:
• (i) a first side portion at the first side of the wall extending from the first load introduction intake structure to the second load introduction intake structure,
• (ii) a second side portion at the second side of the wall extending from the first load introduction intake structure to the second load introduction intake structure and spaced apart from the first side portion,
• (iii) a central portion extending between the first side portion to the second side portion,
• (iv) a first reinforcing portion above the central portion and spaced apart from the central portion, and the first and second side portions,
• (v) a second reinforcing portion below the central portion and spaced apart from the central portion, and the first and second side portions;
• wherein the load-bearing wall element is a sandwich structure comprises a cavity defined by the first and second load introduction intake structures, and the shear-resistant layer, wherein the cavity is sealed by the first and second support plates, and the first and second fiber-containing matrix layers.
