"The steel fibre reinforced concrete (SFRC) is more and more frequently used as material for the lining of underground structures. SFRC has been already used for many applications of sprayed concrete (mostly as primary linings) and also for many applications as precast concrete as segmental lining constructed behind circular tunnelling machines. Polypropylene (PP) fibres are often added to the cast-in-place secondary lining to improve their fire resistance; the secondary linings are either from reinforced concrete or from plain concrete (cast-in-place SFRC is not used for this type of lining)."@en . .
