The making of concrete skin
Nov 9, 2009

The technology and production processes of glassfibre concrete have been perfected for decades and tested practically for more than 30 years. A special extrusion process incorporates layers of glassfibre into a concrete matrix; in the top layer and underlayer the fibres are undirected and scattered, in the medium layer they take the form of rovings (fibre bundles). The omission of steel reinforcement allows the construction of "slim" concrete elements which are highly stressable despite being extremely thin-walled. The result is an extremely thin slab with 8 to 13 mm thickness, which is very light-weight, yet has a high flexural strength. The slabs can be dyed in different colours before being hardened for 28 days.
