Concrete Mix Coloring Powders
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Your Partner in Precision Batching
Deqing Demi Pigment Technology Co., Ltd. is a global leader in providing coloring solutions for the ready-mix and precast industries. We understand that in a high-volume concrete plant, speed and accuracy are everything. Our mix-grade powders are the result of decades of refining mineral chemistry to provide a "hassle-free" coloring experience. We pride ourselves on providing the reliability that concrete producers need to deliver perfect results to their contractors, every single time.
Concrete Mix Usage Areas
- Ready-Mix Trucks: Direct-to-drum coloring for large-scale onsite pours.
- Precast Elements: Uniform coloring for architectural panels and stairs.
- Bagged Ready-Mix: High-purity colorants for retail "just-add-water" concrete.
- Industrial Slabs: Durable coloring for heavy-duty warehouse flooring.
Concrete Mix Technical Specs
| Metric | Value | Standard |
| Fineness (Residue 45$\mu$m) | Max 0.2% | ISO 787-7 |
| Tinting Strength | 100% ± 5% | ISO 787-24 |
| Alkali Stability | Grade 5 | DIN 54001 |
| Chloride Content | < 0.01% | ISO 1157 |
| Water Absorption | Neutral | ASTM C979 |
Core Advantages
- Integral Permanence: The color is part of the concrete structure, not just a film.
- Dust-Reduced Processing: Engineered to minimize airborne particles during loading.
- Non-Fading Hue: Absolute UV stability ensures the mix stays vibrant for decades.
- Structural Safety: Guaranteed not to impact the 28-day PSI rating of the mix.
Q: Can I mix these powders with other admixtures?
A: Yes, our powders are compatible with most plasticizers and air-entraining agents without chemical interference.
Q: What is the maximum dosage?
A: We recommend a maximum of 10% by weight of cement, though 3-5% usually achieves full saturation.
Batching Precision Services
We provide "Custom Dosage Charts" based on your specific local aggregate and cement color, ensuring you hit your target shade on the first try.
Meltable Bag Solutions: We offer pre-weighed, biodegradable bags that can be tossed directly into the mixer, eliminating the need for weighing and reducing site waste.
The Science of Aggregate Coating
In concrete mix science, we focus on the "Surface Energy" of the pigment. For a mix to look uniform, the pigment must coat both the fine cement particles and the larger sand grains. We treat our powders to have a "Universal Wetting" capability, ensuring the color doesn't just "float" in the paste but adheres to every surface. This prevents "color-bleeding" at the edges of the slab and ensures a rich, multi-dimensional aesthetic.
