Laminated composite construction board

摘要

In a composite construction board with a core layer of light concrete produced as a pre-mix, expanded clay beads, produced by firing clay granules at above 1,000 deg C, are mixed into the core layer as light aggregate. Textile glass fibres of various lengths may be provided as an alkali resistant reinforcement of the cladding layers and/or alkali resistant glass or synthetic fibres may be added to the core layer matrix.
