Abstract

1. Paper-, cardboard- or paperboard-like material manufactured by forming sheets from a suspension of aqueous and fiber-like materials and dehydration of said suspension on a sieve followed by drying, with the rigidity of a sheet depending on the hydrogen bridges arising between the individual fibers during dehydration, characterized in that as filler material which is able to bond hydrogen bridges crystalline calcium hydrosilicate having a xonotlith structure with the formula 6 CaO x 6 SiO2 x nH2 or Ca [(OH)2 Si6 O17 ] x nH2 O comprising an original water content exceeding the crystal water content of 2.5 or 3% by weight is provided for, which water content is included in hydrogen bridges between the fibers for supporting the rigidity of the sheet.
