Enhanced Fire Protection through Plastic Fibres in Concrete

Preventive fire protection for tunnels has gained in importance in recent years. Owing to fire disasters in road tunnels new concepts were developed, which have the main purpose of protecting the tunnel concrete. In the interim it is known from a number of research projects and practical applications that adding plastic fibres can lead to substantial or even complete reduction of concrete spalling with an explosive effect. The “Metro Copenhagen” and “Westtangente Bautzen” construction projects as well as the redevelopment of the tunnel at Schlüchtern represent various opportunities for...
