AWMC
Active Cementitious Matrix Filler (ACMF)
ACMF is the base for the creation of high-value concrete mixtures. It is formed by milling selected chalcedonite aggregate using a high-pressure roller mill. Thanks to the unique aggregate milling technology, we guarantee a reproducible granulometric curve, which includes:
- 5% natural white pozzolana;
- 30% active silica filler
- crushed aggregate up to 2 or 4 mm.
Fraction types:
- 2-4 mm (dried)
- 1,25-2 mm (dried)
- 0,8-1,25 mm (dried)
- 0,25-0,8 mm (dried)
Data sheets for all fractions issued on request.

| Bulk density | 1100–1150 kg/m3 |
| Stressed density | 1250–1300 kg/m3 |
| Humidity | up to 7% |
- Product available in bulk.
