Behaviour of hybrid steel fibre reinforced self compacting concrete using innovative hooked-end steel fibres under tensile stress

The use of steel fibre hybridisation with different aspect ratios have been seen to enhance the pre and post cracking response of concrete, however the invention of new innovative macro hooked ends steel fibres with multiple hooks and increase in its linear length have been recently investigated. The results show that the new innovative macro hooked ends steel fibre with multiple hooks performed better than single hooked ends steel fibre with respect to material properties when used in self-compacting concrete. Therefore, the need to further investigate the performance of this new innovative macro (MAC) hooked ends steel fibre when combined with straight micro (MIC) steel fibre of the same aspect ratio in self-compacting concrete would be useful in the study of the stress-strain curve relationship of this composite material.
