Green Iron Oxide for Construction Use
High-performance inorganic pigment with excellent color stability, weather resistance, and broad application range.
Building a Sustainable and Vibrant Landscape
Deqing Demi Pigment Technology Co., Ltd. is the global leader in permanent construction color. We recognize that for urban designers, green represents longevity and nature. Our construction-grade green is manufactured to meet the highest safety and durability standards. We provide the "Permanent Green" that allows architects to bring natural aesthetics to concrete infrastructure with the total confidence that the color is as enduring as the stone itself.
Construction Green Usage Areas
- Concrete Pavers: Durable green for park pathways and pedestrian zones.
- Roofing Tiles: UV-stable green for cement-based and ceramic roofing.
- Industrial Flooring: Hard-wearing green for warehouse and factory floors.
- Artificial Grass Infill: Non-toxic, weather-proof coloring for synthetic turf.
Construction Green Technical Specs
| Metric | Value | Standard |
| Cr2O3 Purity | Min 98% | ISO 1248 |
| Alkali Resistance | Grade 5 (Excellent) | DIN EN 12878 |
| Lightfastness | 8 (Maximum) | ISO 105-B02 |
| Water Solubles | Max 0.3% | ISO 787-3 |
| Sieve Residue (45$\mu$m) | Max 0.3% | ISO 787-7 |
Core Advantages
- Total UV Permanence: Will not fade or "grey out" even in intense sunlight.
- Extreme Hardness: Acts as a functional filler that improves surface abrasion.
- Chemical Resistance: Immune to acid rain and aggressive cleaning agents.
- Eco-Responsible: 100% mineral composition safe for soil and water contact.
Q: Why not use cheaper organic green pigments for concrete?
A: Organic greens (like Phthalo Green) often fail in high-alkali concrete, leading to rapid fading. Our chromium green is chemically permanent.
Q: Does it affect the concrete strength?
A: No, it is chemically inert and does not interfere with the cement hydration process.
Construction Logistics Services
We offer "Water-Soluble Dosing Packs," allowing for precise, dust-free color addition directly into the concrete mixer.
Site-Specific Matching: We can provide custom green shades to match existing park landscapes or historical renovations.
The Science of Octahedral Chromium Stability
The permanence of Chromium Oxide Green in construction is due to its "Trivalent Crystal Structure" (Cr3+). In this state, the chromium atoms are tightly locked in an octahedral oxygen lattice. The science behind our construction grade lies in "Lattice Stability"—this bond is so strong that it cannot be broken by the calcium hydroxide in curing cement or by high-energy UV photons. This ensures the green color is physically inseparable from the concrete matrix.
