Common Crushed Concrete Densities
Standard weight equivalents for recycled and crushed concrete aggregates. Use this table for quick lookups without needing to calculate.
| Material Type | Density (t/m³) | Typical Use Case |
|---|---|---|
| Standard Crushed Concrete (50mm+) | 1.50 | General fill, drainage, non-structural backing. |
| Dense Crushed Concrete / MOT Type 1 | 1.60 | Sub-base for driveways, paths, and foundations. |
| Crushed Concrete with Fines (0-40mm) | 1.70 | Compacted hardcore, trench fill, heavy-duty bases. |
| Crushed Concrete Bulk Bags (850kg) | ~0.53 m³ | Approximate volume of one standard 850kg bulk bag. |
Crushed Concrete FAQ
Everything you need to know about calculating, ordering, and using crushed concrete aggregate.
One cubic metre of standard crushed concrete typically weighs between 1.5 and 1.7 tonnes. The exact weight depends on the size of the aggregate, the amount of fine particles (dust), and the moisture content.
Yes. Larger, single-sized aggregates (like 50mm clean crushed concrete) have more air gaps, making them lighter per cubic metre (around 1.5 tonnes). Smaller aggregates or those with fine particles (like MOT Type 1 or crusher run) pack more tightly, increasing the density to around 1.6 to 1.7 tonnes per cubic metre.
Crushed concrete is recycled concrete broken down into aggregate. MOT Type 1 is a specific, government-approved specification of crushed aggregate (often made from recycled concrete, granite, or limestone) that includes a graded mix of sizes and fines, allowing it to compact firmly for sub-base applications.
First, calculate the volume in cubic metres by multiplying the length, width, and depth of the area (in metres). Then, multiply that volume by the density of the material (e.g., 1.6 tonnes/m³) to find the total tonnage required. It is always recommended to add 5-10% for compaction and wastage.
