TIO2-CONTAINING SUSPENSION FOR THE PREPARATION OF A COMPOSITION WITH PHOTOCATALYTIC PROPERTIES

摘要

The invention relates to a TiO ₂ -containing suspension for the production of a composition with photocatalytic properties, wherein the TiO ₂ -containing suspension 25 to 35 wt .-% micro- or nanoscale silica, 8 to 27 wt .-% TiO ₂ , 1 to 10 % By weight of an aqueous solution containing lignosulfonate and naphthalenesulfonate-formaldehyde condensate and from 0.3 to 2.2% by weight of an aqueous solution of a polyacrylic salt and / or from 0.3 to 2.5% by weight of a silane and / or siloxane containing emulsion. Furthermore, the invention also relates to a production method for concrete using the TiO ₂ -containing suspension.
