consists of small, lightweight, bloated particles of burnt clay.
The thousand of small, air-filled cavities give Huasui LECA its
strength and thermal insulation properties. The base material is
plastic clay which is extensively pretreated and then heated and
expanded in a rotary kiln. Finally, the product is burned at 1100oC
to from the finished Huasui LECA product.
Entirely Natural Product
Huasui LECA is an environment-friendly, entirely natural product
incorporation the same benefits as tile in brick from: Huasui LECA
is indestructible, non-combustible, and impervious to attack by
dry-rot, wet-rot and insects.
Material Huasui LECA is a
natural material and a Huasui LECA building is a healthy building,
so it is no coincidence that Huasui LECA has been used in
competition projects for allergy-friendly, healthy homes.
Used as a thermal-insulation material in
houses, Huasui LECA has been saving energy for more than 50 years,
and is now a standard component in low-energy development projects
in China as well as in many European countries.
Huasui LECA is an extremely lightweight,
strong and thermally insulating material. These are valuable
properties when establishing solid based floors, applying
structural fill, growing plants, and insulating basements,
terraces and roofs. The size of the Huasui LECA particles
determines which property is predominant and how the product is
utilized in practice. Huasui LECA is therefore available
indifferent size for different purposes.
Huasui LECA is the prime constituent in many
building materials, including industrially-made wall blocks and
structural components. Huasui LECA can also usefully be employed
in structural concrete fill and lightweight concrete.
