SUMMARY:Testing of sprayed fibre reinforced concrete for the design of tunnel linings
DESCRIPTION:Overview\nFibre reinforced concrete (FRC) design has been widely used for sprayed permanent linings in tunnels with substantial recent developments in design methods and mix design. One such development has been reliance on the toughness characteristics to inform the design versus the different methods of panel testing. This presentation discusses the 2025 fib bulletin 116 recommendations with a focus on testing and performance criteria. By adopting EN 14488-3 procedure for the toughness characterization of the sprayed FRC\, it is possible to derive the key parameters that are necessary for the design according to fib Model Code 2010 in an easy quantifiable manner. \nLearning outcomes\nIn this presentation\, you will: \n\nunderstand the advantages and drawbacks of various shotcrete testing methods\nunderstand the importance for shotcrete testing to directly relate to design methods\ngain an insight into the latest shotcrete testing methods.\n\nProgram\nIn-person: \n\n5.30 pm AEST: Registrations open\n6.00 pm AEST: Presentation begins\n6.45 pm AEST: Q&A session\n7.00 pm AEST: Networking\n8.00 pm AEST: Event ends\n\nAbout the speaker\n\n\n\nCheng Chian Gan\nTechnical Manager\, Underground Solutions – Bekaert Singapore\n\nGan is an expert in sprayed fibre reinforced concrete with over 35 years of civil engineering experience. He is a member of the Working Group on SS674-2021 since Jan 2019. Gan is a domain Expert for Sprayed Concrete and Fibre Reinforced Concrete under Intelligent National Productivity and Quality Specification Singapore since Mar 2019. From 1998 to present\, Gan has been involved in over 22 sprayed fibre concrete tunnel linings and over 20 fibre concrete precast segmental and cast concrete tunnel lining projects.
