The effects of steel mesh and steel fibre orientation on strength properties and stress- strain behaviour of Slurry Infiltrated Fibre Reinforced Concrete (SIFCON) have been studied. In this research, steel mesh of 0.62 mm diameter and aspect ratio of steel fibers 50 mm were used for preparing the specimens. Steel mesh of different percentages (5%, 10% and 15%) was added in parallel orientation and steel fibers were added with 5%, 10% and 15% in both random and parallel orientation. The results of SIFCON and FERRO cement were compared with the normal cement mortar. FERRO cement and SIFCON showed better results on strength parameters and stress-strain behaviour compared to normal cement mortar.
