5-20 mm diabase crushed stone is the most versatile and in-demand aggregate. The blend of fine and medium grains forms a well-graded matrix that minimises voids, reduces cement paste demand and increases mix density. Cubical shape and low flakiness ensure strong inter-particle interlock and stable behaviour in both concrete and asphalt.
Used in ready-mix concrete M300-M500, heavy concrete for foundation slabs and columns, precast products, and in asphalt concrete mixtures for highways, bridge decks and airfield runways. Technical specs (M1400 / F300 / abrasion I-1) match granite-class aggregates while remaining workable for placement and compaction.
Logistics: direct rail shipments from the Sartauskoye-8 deposit to any region of Kazakhstan — Aktobe, Atyrau, Mangystau, Uralsk, Tengiz, Karachaganak, Kulsary. Request a quote with your destination station and we will confirm volumes and lead times.

Frequently asked questions
How much does 5-20 mm cube-shaped crushed stone (diabase) cost?
Retail price of 5-20 mm cube-shaped crushed stone (diabase) at HKC is 4,900 KZT/t including VAT, with wagon loading at Bershogyr station included. Wholesale terms are available for large buyers — contact our manager.
What is the difference between cubic-shaped and ordinary crushed stone?
Cubical grain shape (flakiness ≤10%) produces tighter packing. In concrete this means lower cement consumption for the same strength grade — up to 10-15% saving. In asphalt, cubical aggregate delivers better bonding with bitumen and a longer pavement life.
What is the minimum order?
Minimum order — 1 rail wagon (about 69 tonnes). For large projects we assemble trains of any size. Truck shipping is not offered — rail only.
Which destinations do you serve?
We ship by rail across Kazakhstan from our siding at Bershogyr station (Shalkar district). Primary destinations: Atyrau, Mangystau (Aktau), Aktobe, Uralsk and other regions. Delivered prices on request.
Which documents are provided?
Every batch ships with a quality passport, test reports and conformity certificate per GOST 8267-93. Tender packs include a radiological report.
