4. Conclusion This research investigated the effect of hybrid fibres with different fibre lengths and volume fractions on post cracking behaviour using fracture and non-destructive testing. The findings have been summarized below.  Compressive strength of 126 MPa has been achieved with ultra-fine material and dense microstructure.  The incorporation of 2% fibres demonstrates a more pronounced impact on both the peak load and post peak behaviour of the material.
