One of the fastest growing markets for iron oxide pigments is decorative architectural concrete. Iron oxide pigments (IOPs) are the lifeblood of decorative concrete and a means of architectural expression. Only IOPs offer the combination of cost-effectiveness, lightfastness, durability and cement compatibility that makes colored concrete feasible. While other types of pigments have these properties, they cost several times as much as IOP. Even with IOP, the cost of pigments can be double the material cost of regular concrete, which means that other pigment types are too costly for 99% of colored concrete projects.

Why is iron oxide so popular in construction?

Iron oxide pigments produce rich, long-lasting color in concrete and other cementitious materials. This pigment has five basic components that explain it:
Good weathering resistance.
good light resistance.
Excellent resistance of concrete to alkaline environments
tinting power (hence vibrant colors).
Fine dispersion
This means that iron oxide pigments do not deteriorate over time through a variety of irritations such as rain, extreme UV exposure and shoe rubbing. Therefore, it is assumed that a good and long-lasting color for concrete can be achieved with just one iron oxide.

How to use iron oxide pigment in concrete

The amount of iron oxide pigment in concrete products is limited to 1% to 10%. Exceeding the upper limit will reduce the mechanical strength of the products. Generally 5%~8% is appropriate.
Iron oxide pigment does not contain two compounds, lead oxide and zinc oxide, which will affect the setting time and strength.
Sometimes, concrete products need to be cured at temperatures and pressures above 200°C. Therefore, black iron oxide and brown iron oxide, which can be converted to red iron oxide at 180°C, must be heat stabilized.
Cement concrete pavement mixed with iron oxide pigment should not be too thick at one time. Generally not more than 20cm. too thick will cause the waste of iron oxide pigment for concrete, which is not economical and cannot guarantee the quality of concrete itself.
