Tunnel linings

In a EUREKA project called COMPRESIT, the concept of CRC tunnel linings was developed. The project included determination of a number of CRC properties and design, production and testing of CRC linings with a strength and ductility equal to that of cast iron linings. The project demonstrated that CRC was a cost effective alternative to cast iron linings in a number of cases, as the design of CRC is much more flexible with the wide range of dimensions and properties which can be used. The price for a CRC lining can be less than a third of the price of a cast iron lining. The project, which included Danish and British participants, was supported by the Danish and British Agencies for Trade and Industry.
