New developments in Alkali-resistant glass fibre for concrete
Over the last years a lot of improvements and new developments have been made for the concrete reinforcement by Alkali-Resistant Glass fibres. One of the most important are new reinforcement, like meshes or mats, allowing higher reinforcement rates or other performances like impact or post-rupture behaviour, have been developed and proposed to the market. This has allowed the concrete manufacturers to propose new applications, both in the architectonic markets (example: tunnel cladding in France, monument in Singapore), and industrial pieces like riverbank protections or insulation systems. Alkali-Acid Resistant Glass (AR Glass) is a glass composition containing at least 15 % of Zirconia (Zr02). This is, until now, the only way to have glass fibres, which will resistant to the alkali medium of cementious matrices, and maintain the performances over the years. The range of possible applications of these products is wide. In wall rendering or external insulation finish systems, the use of AR mesh offers a more durable alternative to coated E-glass products giving added security. Mat or mesh can also give enhanced performance as localised reinforcement in various moulded products such as architectural components, duct covers, or raised floor tiles, notably where there is a specific technical requirement. A major use area for mat or mesh is for reinforcement of standard products made by auto process. New systems of industrialised sheet-forming processes, like the Wellcrete or Durapact, are being developed based on this kind of reinforcement. In France the recent developments are of special panels: in service adjacent to roadways, any wall cladding material is exposed to chemical agents in the form of anti-icing salts, cleaning materials or car engines fumes, etc. These severe service conditions require a material to have both high long-term properties, and high impact resistance. This may be achieved by using both metakaolin in the mix, and AR Glass mesh in the back of the panels. A recent project has been using this kind of panel in the Saint-Cloud tunnel on the A13 Autoroute.
