Description & Application:
Top quality genuine expanded lightweight aggregate manufactured by Lecaź . Specifically recommended where a high volume lightweight sand is required. The product can be used for general building with either lime or cement to provide render backing coats. The product is also extensively used in block making and pre-fabricated lightweight concrete manufacture.

The product is suitable in situations where aesthetics are not a prime consideration, in particular, blended with other growing media to improve drainage and provide insulation.

Expanded clay granules are made by pelletising and firing clay in a rotary kiln at a very high temperature. As it is fired, the organic compounds in the clay burn off forcing the pellets to expand and become honeycombed while the outside surface of each granule melts giving a ceramic shell. The resulting granules are lightweight, porous, and have a high resistance to crushing.

Being a natural product expanded clay aggregate contains no harmful substances, it is inert with a neutral pH, The granules are resistant to frost and chemicals, and will not break down in water. They are also non-combustible and have excellent sound and thermal insulation properties.
