Iron Oxide pigment is used as dye or colorant in various prefabricated concrete parts and architectural products and materials. Yellow iron oxide is directly added into cement to color up various indoor and outdoor cement surfaces, i.e. walls, terraces, ceilings, pillars, corridors, roads, car-park, stations, etc, as well as various building ceramic and glazed ceramics, i.e. facing bricks, floor tiles, roofing tiles, panels, terrazzo, mosaic tiles, artificial marbles, etc.
Iron oxides are chemical compounds composed of iron and oxygen. widespread in nature, play an important
role in many geological and biological processes, and are widely used by humans, e.g., as iron ores, pigments,
catalysts, inthermite (see the diagram) and hemoglobin. Common rust is a form of iron(III) oxide. Iron oxides
are widely used as inexpensive, durable pigments in paints, coatings and colored concretes. Colors
commonly available are in the "earthy" end of the yellow/orange/red/brown/black range.
