Ultra-high-performance concretes reliably colored with Bayferrox

摘要

Ultra-high-performance concretes are regarded as the construction material of the future. In coloring them, however, it must be ensured that the specified compressive strengths of over 150 MPA continue to be reached. The iron-oxide pigments of the Bayferrox brand from Lanxess have been proven to be suitable for use in UHPC. This was confirmed by the Association of German Cement Works (VDZ), based on investigations of compressive strength in accordance with DIN EN 12390-3."Architects and builders are on the safe side when coloring UHPC with our high-quality pigments," emphasizes Oliver Fleschentraeger, Market Segment Manager Construction in the business area Inorganic Pigments at Lanxess. The choice of color comprises red, yellow and black iron oxides. Within this color group, a wide range of color shades is possible. "Bayferrox pigments, to our knowledge, are the only iron-oxide pigments on the market that are especially certified for reliable use in UHPC," points out Fleschentraeger.
