Bulk density by fraction
The values the calculator uses. More detail on the Crushed stone density page.
| Fraction | Bulk density, t/m³ |
|---|---|
| 5-10 mm | 1,464 |
| 5-20 mm | 1,520 |
| 10-20 mm | 1,490 |
| 20-40 mm | 1,474 |
| 25-60 mm | 1,40 |
| 40-70 mm | 1,380 |
| 0-5 mm (screenings) | 1,480 |
| 0-40 mm (mix) | 1,60 |
| 0-70 mm (mix) | 1,62 |
| 0-80 mm (mix) | 1,65 |
Frequently asked questions
How do I convert tonnes of crushed stone to cubic metres?
Volume (m³) = mass (t) ÷ bulk density (t/m³). Pick a fraction in the calculator — density is filled in automatically.
How many wagons do I need for my volume?
The calculator divides tonnage by 69 t (one HKC wagon) and rounds up. E.g. 500 t → 8 wagons.
Which density is used in the calculation?
Bulk density of HKC diabase by fraction — from 1.38 t/m³ (40-70 mm) to 1.65 t/m³ (mix 0-80). Values are indicative; exact batch density is in the quality passport.
