Highlights
Steel fibres are used in sprayed concrete to provide post-cracking reinforcement to enhance toughnesss avoiding the typical brittle behavior of this material (Bernard and Thomas 2020) and enhancing dynamic mechanical properties (Chen et al 2020)
The study showed the possibility of correlation between the results obtained of energy absorption in the Barcelona test (BCN) tests in small and large extracted cylinders and the square panel test EN 14488-5
It was confirmed that the level of energy absorption is directly related to the actual fibre content of the Steel fibre reinforced sprayed concrete (SFRSC), being able to determine which energy level corresponds to each test for a given fibre content
Summary
Steel fibres are used in sprayed concrete to provide post-cracking reinforcement to enhance toughnesss avoiding the typical brittle behavior of this material (Bernard and Thomas 2020) and enhancing dynamic mechanical properties (Chen et al 2020). Steel fibre reinforced sprayed concrete (SFRSC) is widely used in a variety of applications including, construction of slope stabilization, excavation support, structure recovery, refractory lining, tunnel lining, mining operations, etc. Specifications (e.g. EFNARC 1996, EN 14487-1 2005) classify the SFRSC in this application according to the material energy absorption capacity measured in flexural tests of square panels. The Australian Institute of Concrete (2010) takes the energy absorption class measured in the square panel test and the rock formation as input parameters for the tunnel lining design
