Laterlite Expanded Clay is a lightweight aggregate (LWA), with insulating characteristics made by expanding special natural clays at high temperature (1200°C). Laterlite Expanded Clay is manufactured in different types and sizes, in granular or crushed form, standard (lighter and insulating applications) or structural (high mechanical strength applications). Laterlite Expanded Clay aggregates uniquely combine low density and thermal insulation with high mechanical strength, which is achieved thanks to the, clinkerised rigid outer shell surrounding the internal cellular structure of the granules. These properties make Laterlite Expanded Clay extremely versatile, finding multiple uses in construction and civil engineering, loose on his own or mixed with binders (cements, lime, resins…), for insulation, drainage, or reduction of dead loads. These characteristics are also highly valued when used in the production of blocks, mortars, screeds, concretes, and refractory products, in a wide range of densities and strengths. FIELDS OF USE • Lightweight and insulating backfill. • Lightweight and insulating floor substrates. • Flat and sloping roofs (slopes, screeds, insulation, etc.) • Drainage • Lightweight embankments and other geotechnical and civil engineering applications • Landscaping and green roofs • Structural and non-structural lightweight concretes • Prefabricated concrete elements. • Bituminous conglomerates for road surfaces • Refractory insulation, concretes and mortars • Road de-icing dispersions (environmentally friendly alternative to salting) • Water treatment
