Carbon Black for Cement and Black Cement Production
Black Gold Chemicals manufactures water-soluble and pigment carbon black for the cement industry. Our grades color cement for black cement and plaster, and work as a grinding aid that shortens grinding time and gives finer particles.
Two roles in cement: color and grinding aid
Carbon black is used in the cement industry in two ways. As a pigment, it turns grey cement into black cement for plaster, roofing, and decorative concrete. As a grinding aid, it helps the mill work faster and produce a finer, free-flowing powder.
What our cement grades deliver
- Deep black cement: strong coloring for black cement and plaster.
- Shorter grinding time: as a grinding aid, it helps the mill reach the target fineness faster.
- Finer particles: a finer product from the same grinding process.
- Better powder flow: improves the flowability of the dry powder for easier handling and packing.
- Water-soluble and pigment grades: choose the type that fits your process.
- Batch-to-batch consistency: every batch is produced to defined parameters.

Frequently asked questions
Can carbon black be used as a grinding aid?
Yes. Added during grinding, it can shorten grinding time, give finer particles, and improve the flow of the dry powder. The right dosage depends on your mill and cement type, so we recommend a trial.
Which grade do I need for black cement?
It depends on your process and target shade. We supply water-soluble and pigment grades and will recommend the one that fits after reviewing your needs.
Do you provide a TDS?
Yes. Once we identify the right grade for your application, we send its TDS and SDS.
Can I get a free sample?
Yes. Contact us with your application and we will send one.
