Assessing toughness characterization of sprayed FRC by adopting EN14488-3 2022 Method B

Event overview

Fibre 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 characterisation 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.

The presentation will also highlight the advantages and drawbacks of various shotcrete testing methods, the importance for shotcrete testing to directly relate to design methods, and an insight into the latest shotcrete testing methods.
