LIGHTWEIGHT, INSULATING, STRONG, NATURAL NON-COMBUSTIBLE AGGREGATE.
FOR WEIGHT REDUCTION, INSULATION, BACKFILL, DRAINAGE, AND IN LIGHTWEIGHT CONCRETES AND MORTARS, GARDENING, AND AGRICULTURE
Laterlite Expanded Clay is a lightweight aggregate made by expanding special natural clays at high temperature (1200°C). It is supplied either as granules in a range of sizes or as a crushed version, with a unique set of characteristics.
Lightweight, insulating, strong: Its porous internal structure means it is lightweight (from approx. 320 kg/m3), thermally insulating (from lambda [?] 0.09 W/mK) , and sound-absorbent. The vitrified 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: It 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 that is ideal 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.
