METHOD FOR PRODUCING PULVERULENT SOLIDS FROM ALKALI SALTS OF SILANOLS

摘要

The invention relates to a method for producing pulverulent solids (F) which comprise alkali organosiliconates. Water is removed from aqueous solutions of alkali organosiliconates with a molar ratio of alkali to silicon of 0.1 to 3, an alcohol content of less than 0.1 wt.%, and a halide anion content of maximally 1 wt.% by means of spray drying. The invention also relates to pulverulent solids (F) which can be produced using the method, to construction material mixtures containing solids (F), and to components or molded bodies which can be produced from the construction material mixtures.
