Iron Oxide Powder For Concrete

Iron oxide pigments produce vibrant, subtle colors in concrete and other cementitious materials. Iron oxide pigments do not deteriorate over time and are easily visible in the 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 present a uniform color.
Iron oxide pigments do not affect the strength or ease of concrete when used in standard dosages. They offer many benefits to concrete contractors, architects, ready-mix producers and manufacturers of precast concrete products. Iron oxide pigments can significantly increase the value of concrete. By adding color, concrete becomes more attractive and provides color-related properties such as solar reflectivity.

Iron oxide pigments maintain color stability during the preparation process and do not change color when exposed to heat or light.

Iron oxide pigments are widely used in coatings, paints, plastics, rubber, ceramics, asphalt, cement and other fields to provide color stability and uniform tinting effect.

Iron oxide pigments are widely adopted for their stability, weather resistance and versatility, and their relatively low cost makes them a cost-effective choice for making a wide range of color products.

Iron oxide pigments have excellent weathering resistance, with high resistance to light, chemicals and climate change, and are not easily faded or discolored.

Iron oxide pigments are extremely light stable and can therefore be exposed to outdoor environments for long periods of time without noticeable color fading.

$Iron oxide pigments remain stable at high temperatures and are therefore often used in products that are resistant to high temperatures, such as ceramics or refractory materials.$

Iron oxide pigments remain stable at high temperatures and are therefore often used in products that are resistant to high temperatures, such as ceramics or refractory materials.

Iron oxide pigments are mainly composed of iron and oxygen elements. Depending on the oxidation state, they can be formed into a variety of colors, such as red, yellow, brown and black.

Compared to some other pigments, iron oxide pigments are often considered an environmentally friendly choice as they contain no heavy metals or other harmful substances.

Because iron oxide pigments are available in a variety of oxidation states, a wide range of colors can be achieved through different formulations and treatments, from bright to deep.

Iron oxide pigments have excellent covering ability, which can effectively hide the color or imperfections of the underlying layer when covering the surface.

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 various irritations (e.g. rain, extreme UV exposure and shoe rubbing). Therefore, assuming good and long-lasting color for concrete is only a small step away from iron oxide.

There are four key components that every manufacturer should keep in mind when using iron oxide pigments to color concrete:

Pigment quality: Simply put, good quality pigments are important. Finding a reliable and trustworthy supplier will eliminate problems such as improper mixing and inconsistent color.

Water-to-ash ratio: "The more water, the lighter the color" is easy to remember, but not easy to avoid. Therefore, it is critical to be aware of the amount of water added to the mixture and remember that the effect achieved will be permanent.

Cement content: as previously mentioned, iron oxide pigments react with cement particles, which means it is the basis of the color. To better address this issue, it is recommended to use the same batch of cement and rely on the weight of the cement rather than the "bagged mix" in the formulation.

Aggregate Color: Typically, aggregates are sand and gravel or crushed stone, which do not give the same color to the final product.
