摘要

Process for the production of a mortar for joining ceramic bodies based on a dry mixture, which comprises the following components: a) 50 to 70% by weight of at least one amorphous filler, comprising ground fragments of the ceramic bodies to be joined, -% of at least one fly ash, c) 3 to 20% by weight of at least one metal silicate of the composition M2O · nSiO2, where n = a whole or fractional number between 1 and 5, d) at least one porous auxiliary, and e) at least one Phosphate or polyphosphate as hardener for the metal silicate, characterized in that the method comprises the following steps: A) adding water to the dry mixture, B) mixing the water with the dry mixture to form a uniformly wetted mortar, with no further liquids and basic hydroxyl compounds added be added to the dry mix.
