How Many kg is 1 m³ of Perlite?
Perlite weight is not constant. Because expanded perlite has a very lightweight and porous structure. Therefore, the kilogram value of 1 m³ of perlite varies according to its density.
How Many kg is 1 m³ of Perlite?
In general:
- 1 m³ expanded perlite: varies between 30 kg – 150 kg
Detailed Values Based on Density
| Perlite Type | Density | 1 m³ Weight |
|---|---|---|
| Ultra-light perlite | 30 – 50 kg/m³ | 30 – 50 kg |
| Standard construction perlite | 60 – 100 kg/m³ | 60 – 100 kg |
| Dense perlite | 100 – 150 kg/m³ | 100 – 150 kg |
Why Does It Vary?
The weight of perlite depends on the following factors:
- Expansion ratio
- Grain size
- Intended use (plaster, screed, agriculture, etc.)
- Moisture content
Sample Calculation
If the perlite density is 80 kg/m³:
1 m³ perlite = 80 kg
Conclusion
Since perlite is a very lightweight material: 1 m³ of perlite is generally accepted as 60 – 100 kg. However, for the exact value, the product's density information must be checked.
