Why diabase for concrete and precast
High-grade concrete and precast units depend on strength, grain shape and batch consistency:
- 100% cubic shape, flakiness ≤10% — dense packing in concrete, up to 10% cement savings for the same strength grade. Competitors charge 30–40% more for a cubic shape; for us it is standard.
- M1400 — margin for concrete M400–M500 and above.
- Low reactivity with cement — durability of precast reinforced concrete.
- F300 — for the continental climate of the Aktobe region with sharp seasonal swings.
For concrete plants and precast factories in Aktobe, cubic diabase means a stable concrete grade at lower cement consumption.

FAQ — Aktobe
Do you deliver crushed stone to Aktobe?
Yes. The quarry is in the Aktobe region; we ship by rail from Bershogyr to Aktobe station — a short haul. Minimum batch — 1 wagon (≈69 t).
Which crushed stone for concrete M400 and precast?
The best are 5-20 (universal) and 20-40 (heavy units). Strength must be at least M800; HKC diabase M1400 has a large margin. The cubic shape saves up to 10% cement.
Which crushed stone for asphalt concrete?
For top layers — 5-10 and 5-20 with abrasion I-1 (as HKC has). Cubicity improves binder adhesion and extends pavement life.
