- light weight
- large exterior and interior surfaces that facilitate water films to form
- low salinity
- Specific pH---clay pebble's pH value is between 6-7.
2. Insulation/Construction material
- Thermal Insulation
- Sound Insulation
- Fire resistance
- Non-decomposability
- Water absorption etc.
Usages: Loose cell filling, Roof insulation, Road Construction
Aggregates, Light weight aggregate concrete block etc.
3. Water treatment: Wastewater---Biofilter, Filtrations
For home wastewater treatment, Leca/Expanded clay aggregate can replace distance gravel in aerobatics filter manufacturing.
And also in anaerobic filters, the porous of Leca/Expanded Clay aggregate is a suitable environment for growth of useful bacteries.
