In recent years, fibre reinforced concrete (FRC) has been used in underground construction for sprayed concrete in underground support linings. The evenly distributed fibres contributed to considerable increase in load-bearing capacity, durability and impact resistance. This paper aims to present the definition, design, performance specification and the latest QA/QC test methods of sprayed FRC. The QA/QC requirements will also be in line with the latest Singapore Standard SS 674: 2021 - Design of fibre concrete structures.
