<p>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.</p> |
