|Abstract||Results of an investigation conducted to comparatively evaluate the strength and flexural toughness of Self-Compacting Fibre-Reinforced Concrete (SCFRC) containing different volume fractions of steel fibres are presented. An experimental program was planned, in which beam specimens of size 100 x 100 x 500 mm were tested under four-point static flexural loading to obtain the flexural strength and load-deflection curves of SCFRC. In addition, cube specimens of size 150 x 150 x 500 mm were tested to obtain their compressive strength. The specimens incorporated steel fibres in the volume fractions of 0.5%, 1.0% and 1.5%. A suitable SCFRC mix was designed incorporating 33% fly ash. The flexural toughness parameters were obtained following the procedure described in ASTM C-1018 C, JCI Method and ASTM 1609/C 1609M and using Post-Crack Strength (PCS) method. The results indicate that there are significant increases in the compressive strength, flexural strength and flexural toughness characteristics of SCFRC with the increase in volume fraction of steel fibres.|
