The Norwegian Concrete Society has been a leading participant regarding the use of wet-mix sprayed concrete for many years. It is therefore with great pleasure that we announce the Sixth International Symposium on the MODERN USE OF WET-MIX SPRAYED CONCRETE FOR UNDERGROUND SUPPORT. This conference will be located in Tromsø, in the north of Norway. We sincerely hope that many of our international colleagues will again take the opportunity to present papers, exchange experiences and discuss the latest developments in wet-mix sprayed concrete. The main symposium themes will be design, construction and durability of wet-mix sprayed concrete in underground structures. In view of the latest incidences in Norway regarding failure in the rock support system in a highway tunnel, the support philosophy has been heavily debated in Norway. The Norwegian Concrete Association is currently revising the Publication No 7, Sprayed Concrete for Rock Support – Technical Spesification, Guidelines and Test Methods. This publication will be debated during the symposium. Wet-mix sprayed concrete technology has been further developed to a much higher level since the first symposium in 1993, with the latest developments in chemical additives, application equipment and fibers. It will continue to change, and the sixth International Symposium in Tromsø will ensure that delegates are kept abreast of the new developments in the use of this material. Tromsø – the gateway to the Arctic We are looking forward to see you at the symposium in Tromsø in the autumn of 2011. |
