LECA (Light Expanded Clay Aggregate) is a lightweight, durable aggregate made by expanding natural clay at high temperatures. It is widely used in construction, agriculture, and landscaping for its strength and insulation properties.
Leca is produced by heating and expanding natural clay in a rotary kiln at temperatures of up to 1,200°C. This process creates porous, lightweight aggregates with exceptional strength.
Leca is made from natural clay, which is heated and expanded to form lightweight, durable aggregates.
- Lightweight: Reduces structural load.
- Thermal insulation: Improves energy efficiency.
- Sound insulation: Reduces noise transmission.
- Durability: Resistant to fire, water, and chemicals.
Leca can be stored indefinitely under proper conditions, such as a dry and ventilated environment.
The thermal conductivity coefficient of Leca Aggregate is approximately 0.10–0.13 W/mK, making it an excellent thermal insulator.
Yes, Leca has excellent sound insulation properties, effectively reducing noise in construction projects.
Yes, Leca blocks provide exceptional fire resistance and are suitable for use in fire-rated walls and structures.
Leca is chemically inert and does not react with other construction materials, ensuring long-term compatibility and stability.
- Cost savings: Reduces transportation and structural costs due to its lightweight nature.
- Energy efficiency: Decreases energy consumption with superior insulation.
- Longevity: Minimizes maintenance and replacement costs.
Leca is used in:
- Construction (lightweight concrete, foundations).
- Landscaping (rooftop gardens, green spaces).
- Agriculture (soil aeration, hydroponics).
- Filtration (water and wastewater treatment).
