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.
