Investigating Fibre Reinforced Concrete's Strength, Flexibility, and Longevity

Abstract

There have been several difficulties with mesh-reinforced lining constructions because to the complex tunnelling circumstances and varying technical requirements. Thereafter, steel fiber reinforced concrete (SFRC) is promoted as a trustworthy replacement for mesh-reinforced linings. In this study, we take a look at the components and typical characteristics of SFRC. Cracks or structural failures in mesh-reinforced linings are summarized, and contemporary difficulties in this field are discussed. Tunnel linings made from SFRC are discussed, along with the benefits of doing so. In addition, the performance of SFRC in tunnel lining applications is reviewed, along with various design considerations and practical instances. The evaluation found that SFRC lining had a favourable impact on limiting rock movement, decreasing lining pressure, and ensuring both global and local support structure integrity. The study provides useful information for advancing the use of SFRC
