relative density for crusher sand

The relative density (also called specific gravity) of crusher sand (manufactured sand or M-sand) typically ranges between 2.5 and 3.0, depending on the parent rock and crushing process.

Factors Affecting Relative Density:
1. Parent Rock Composition:
– Granite-derived crusher sand: ~2.6–2.7
– Basalt-derived crusher sand: ~2.8–3.0
– Limestone-derived crusher sand: ~2.5–2.7

2. Grain Shape & Porosity:
– Angular particles (common in crusher sand) may have slightly lower density than natural rounded sand due to voids.

3. Moisture Content:
– Dry crusher sand has a higher relative density compared to saturated conditions.

Typical Values:
– Bulk Relative Density: ~1.4–1.6 (loose state)
– Solid Particle Density: ~2.6–3.0 (varies by rock type)

For precise engineering applications (e.g., concrete mix design), lab testing (ASTM C128 or IS 2386-Part 3) is recommended to determine the exact value for your specific crusher sand source.
