The hollow chambers are filled with mortar (14) in a sealed manner. The mortar has high dry density and contains 5 to 30 weight percent of adhesive agents and 40 to 80 weight percent of additives with dense aggregates above 0.25 mm. The mortar contains 5 to 50 percent of filler material below 0.25 mm. A portion of the adhesive agents comprises 1 to 10 weight percent of mineral adhesive agents. The additives comprise quartzite or calcite crushed sand. The filler material comprises brick powder, crushed rock, basalt powder, slag sand powder and/or electrofilter ash. An independent claim is also included for a method for producing a hollow brick.
