Iron Oxide Pigment For Mortar
Iron oxide pigments produce vibrant               , long-lasting colors in concrete and other cementitious materials. Iron oxide pigments are light resistant, insoluble and alkali resistant. This means that iron oxide pigments do not deteriorate over time and are easily visible in concrete. Due to their small size, ten times smaller than cement particles, iron oxide pigments are dispersed in the mixture, embedded in the cement matrix and give a uniform coloring appearance.     
 
When used in standard dosages, iron oxide pigments do not affect the strength or ease of concrete. They offer many benefits to concrete contractors, architects, ready-mix concrete producers and manufacturers of precast concrete products. Iron oxide pigments can greatly enhance the value of concrete. By adding color, concrete is more attractive and offers color-related properties such as solar reflectivity.
