Abstract
For the preparation of a building and/or construction material a polymer modified, aqueous dispersion, containing amorphous silicon dioxide and at least one polymer, is mixed and reacted with at least one inorganic binder, and occasionally with at least one aggregate, and hardens thereby. The polymer modified, aqueous dispersion contains amorphous silicon dioxide and at least one polymer. This polymer modified, aqueous dispersion is used for the preparation of a building and/or construction material.
Claims23
A process for preparing a building and/or construction material comprising admixing a stable aqueous dispersion, containing a noncuring mixture of amorphous silicon dioxide and at least one polymer, with at least one inorganic binder, thereby reacting and hardening the admixture.
A stable aqueous dispersion comprising a noncuring mixture of amorphous silicon dioxide and at least one polymer.
