Formel
Compacted volume = Loose volume / Compaction factor. Shrinkage % = (Loose − Compacted) / Loose × 100.
Häufig gestellte Fragen
What is a compaction factor?
The compaction factor (or swell factor) represents how much loose soil compacts under load. Clay shrinks more than sand.
Why does clay have a higher factor?
Clay has more void space when loose and compacts significantly more than granular soils like sand or gravel.
