SIFCON contains relatively high volume of steel fibres as compared to SFRC. Failure patterns of SIFCON slabs are studied in this paper. SIFCON specimens are cast by varying steel fibres and polypropylene fibres in different ranges of volume separately. Research also arrived at a hybrid combination of fibre for slab and studied the properties. Slab specimens of side 60 cm and height 5 cm are adopted for punching shear studies. Cement, GGBS and Sand are taken in the ratio 1:1:2. Water to binder ratio adopted is 0.45 and super plasticizer dosage is found to be 1%. Steel fibres of Length 25mm, diameter 0.5mm and aspect ratio 50 is used. And Polypropylene fibres of Length 24mm, diameter 0.028mm and aspect ratio 857 is used.
