HKC diabase quality: M1400, F300, Class I
Diabase from the Sartauskoye-8 deposit (Mugalzhar district, Aktobe region) is one of the strongest rocks in Kazakhstan:
Why diabase crushed stone outperforms other rocks
Diabase is an igneous rock that outperforms most alternatives on the Kazakhstan market:
| Parameter | HKC diabase | Limestone | Granite |
|---|---|---|---|
| Strength | M1400 — high | M600–M1000 | M1200–M1400 |
| Frost resistance | F300 | F50–F100 | F200–F300 |
| Radiation safety | Class I | Class I | Often Class II |
| Cubic shape | ✓ Standard | ✗ Flaky | Depends on crusher |
| Price in Kazakhstan | Mid — optimal | Low | High |

Frequently asked questions
How much does 5-20 mm diabase crushed stone cost?
Retail price of 5-20 mm diabase crushed stone 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.
Where is the HKC quarry located?
The quarry sits on the Sartauskoye-8 deposit in Mugalzhar district, Aktobe region, Kazakhstan — one of the strongest rock outcrops of the region, M1400 strength and F300 frost resistance.
How does HKC ship crushed stone?
HKC ships exclusively by rail. Two options: loading into the customer’s wagons on our siding at Bershogyr station, or turnkey rail delivery across Kazakhstan. Truck shipments are not offered.
What is the advantage of cubic-shaped crushed stone over ordinary stone?
Cubical shape delivers tighter packing — concrete uses less cement for the same strength, and asphalt bonds better with bitumen and lasts longer. All HKC crushed stone is cubic-shaped; it is the standard of our line.
How does diabase compare to granite crushed stone?
Diabase is an igneous rock with strength (M1400) comparable to granite but typically 20-40% cheaper and more available in Kazakhstan. HKC diabase is Class I radiation safety; granite is often Class II.
Which crushed stone is needed for M400 concrete?
M400+ concrete requires aggregates with strength of at least M800. HKC diabase at M1400 is a perfect fit. Optimal fractions for M400+ concrete are 5-20 mm and 20-40 mm.
Is HKC stone suitable for railway ballast per GOST 7392?
Yes — 25-60 mm diabase from HKC meets GOST 7392 requirements. M1400 strength and F300 frost resistance ensure long-term track performance.
Is the crushed stone suitable for asphalt mixes?
Yes — thanks to cubical grain shape and high strength, diabase is ideal for asphalt concrete. Best fractions for asphalt plants: 5-10, 5-20 and 10-20 mm for top layers, 20-40 mm for bases.
What is the minimum shipment?
One rail wagon — approximately 69 tonnes.
Which regions of Kazakhstan do you serve?
Primary destinations — Atyrau, Mangystau (Aktau), Aktobe, Uralsk (WKO), and other regions of Kazakhstan.
