The inorganic lightweight material is composed of a mixture that is hydrothermally combined with water vapor at 120 DEG to 300 DEG C and set in molds and that consists of finely ground lightweight aggregate and approximately the same amount by weight of finely ground alkaline earth hydroxide or a dry pourable powder which has surface-adhesive alkaline earth silicate hydrates and/or gels that are produced by bringing silicate-containing lightweight aggregates into contact with aqueous alkaline earth hydroxide, removing the excess liquid phase and then drying the solid phase. |
