(57) It is described a reinforced concrete element (20) comprising a loadbearing plate system (10), comprising two aluminium alloy metal plates (12), wherein each of the metal plates (12) has an outer plate surface (So) and an inner plate surface (Si); a plurality of distance bars (15); wherein the distance bars (15) extend between the respective inner plate surfaces (Si) over a distance (D), wherein the inner plate surfaces (Si) face each other and form an inner volume (Vol) there between, wherein the loadbearing plate system (10) comprises shutters between the metal plates (12) to enclose the inner volume (Vol), wherein the inner volume (Vol) is filled with pourable concrete (25), wherein the pourable concrete (25) is a calcinated clay pourable concrete (25). It is further described a method of fabricating a reinforced concrete element (20).
