Expanded Clay Aggregate ( ECA ® )

Light Expanded Clay Aggregate (ECA), LECA, manufacturer, supplier, India

Light Expanded Clay Aggregate, ECA ® or LECA is a round pellet structure produced by firing natural clay at temperature of 1200°C. The result is a hard, honeycombed structure of interconnecting voids within the aggregate. The particles formed are round in shape and generally range in size from 0-30 mm. These are processed to the required grading, depending on the versatile applications. When the inter-granular voids (voids connecting with one another) are immersed in water they immediately become saturated. The intra-granular pores (Voids within each aggregate) only fill slowly with the water by capillary action and some of them will never become saturated. This results in excellent drainage capacity property of Expanded Clay Aggregate (ECA ®, LECA) due to the network of inter granular pores whilst intra-granular pores helps for water absorption.

European Standard EN 13055-2 signifies the coefficient of water absorption of Light Expanded Clay Aggregate known as ECA ® or LECA by immersion of dry clay aggregate in water for 24 hours. Comparison of its weight before and after test (post drainage) gives the quantity of water that has been absorbed by the granules (results vary depending on the grain sizes of 0-30 mm).

The Expanded Clay Aggregate also known as ECA ® or LECA have a lightweight internal cellular structure with good insulating properties which is enclosed within a compact and strong external shell which provides an excellent weight-strength ratio making the aggregate absolutely suitable for versatile applications including major use in Landscaping, Geotechnical, Construction and Infrastructure applications.

ECA ® is 100% inert, vitrified, dimensionally stable material whose volume remains unchanged in contact with water. ECA ® is reusable and recyclable. Expanded Clay Aggregate (ECA ®) being a frost and fire-resistant material is also a thermally insulating and sound absorbent product. Light Expanded Clay Aggregate (ECA ®) is the only lightweight aggregate certified for geotechnical uses and is marked compliant with EN 15732 (Lightweight fill and thermal insulation products for civil engineering applications (CEA) by CE).

Versatile Applications of Expanded Clay Aggregate - ECA ®

Light Expanded Clay Aggregate – ECA ® is a 'green' building material that helps in a green building practice for its design, construction, or operation, reduces or eliminates negative impacts, and can create positive results on our climate and natural environment.

Light Expanded Clay Aggregate - ECA ®  is a Lightweight green construction material that is 100% inert, non-toxic in nature, ethical, and a sustainable aggregate Some offering thermal insulation by low thermal conductivity coefficient as low as 0.097 W/mK, excellent soundproofing benefits by high acoustic insulation, excellent moisture impermeability, being incompressible under permanent pressure and gravity loads, resistant to decomposing under severe conditions, fire-resistant, having a pH of nearly 7, offering to freeze and melting resistance, offering ease of movement and transportation, ideal aggregate for lightweight backfill and finishing projects, and further offering reduction of dead construction load and lateral earthquake loads in seismic zones.

ECA® is also a green aggregate considered a perfect sweet soil for plants and used as a material for drainage and filtration.
