Characteristics of Expanded Clay

You are here:Home » About us » Expanded clay » Characteristics of Expanded Clay

Lightweight, insulating, strong

Its porous internal structure means it is lightweight (from approx. 320 kg/m3), thermally insulating (from lambda [l] 0.09 W/mK), and sound-absorbent. The ceramic “clinkered” outer shell surrounding the granules makes them very hard and resistant to compression (up to 12 N/mm).

Non-combustible and fire-resistant

This is a 100% mineral non-combustible product (Euroclass fire rating – A1) that is fire-resistant and safe, including in the presence of fire. It is commonly used in refractory applications.

Extremely stable and durable

iIt will not rot, cannot be attacked by parasites (fungus, rodents, insects, etc.), is resistant to acids, bases, solvents, and freeze-thaw cycles, is dimensionally stable and non-deformable, and retains its properties unaltered over time; for all practical purposes this material will last forever.

A natural material for sustainable construction

The natural raw materials used in Laterlite Expanded Clay, its manufacturing process that respects the environment, and the total absence of harmful emissions (even in the presence of fire), make it ideal for sustainable construction as certified by ANAB-ICEA, the Italian Accreditation Institute.

Versatility

Laterlite Expanded Clay is used extensively in construction, both loose on its own or mixed with binders (cement, lime, resins, etc.).

It is widely used as a component of concretes (p. 24-25), in blocks and precast elements (p. 26-27), for agricultural and horticultural applications, and in geotechnical engineering and infrastructure works.

High drainage capacity

Because of its granular nature, which consists of a dense network of intergranular voids with high drainage capacity, it can be used to create lightweight drainage layers of high strength.

CE-marked

It is manufactured and tested in accordance with international reference standards, and is CE-marked to denote conformity to EN 13055-1, EN 14063-1, and EN 13055-2.
