FLYCRETE grades and lines
Product description
FLYCRETE colours are lightfast, alkali-resistant inorganic pigments for cement- and lime-bound materials. Granules and slurries suit automatic dosing systems; blends are matched to the customer’s shade card in their own concrete.
Forms

Typical properties
| Property | Typical value | Method |
|---|---|---|
| Colour strength | 100 ± 5 % of standard in reference mortar | Mortar prism |
| Water-soluble content (powders) | ≤ 0.5 % (target) | EN 12878 method |
| Effect on setting and strength | Within EN 12878 limits (target) | EN 12878 |
| Slurry solids | 55–70 % | Gravimetric |

Use
- Dosage
- 1–5 % pigment on cement weight; little extra colour above about 6 %
- Order of addition
- Add with the aggregates, mix, then add cement and water; extend mixing by 60–90 s for powders
- Good practice
- Keep water-cement ratio, cement source and curing constant; efflorescence can mask colour; use white cement for light and bright shades
- Black
- Use iron-oxide black; carbon black is not recommended in concrete
Storage and packing
- Powders and granules
- Dry; 36 months; 25 kg bags and big bags
- Slurries
- 5–35 °C, frost-free, stir or recirculate; 6 months; 1,000 L IBC
