Abstract: Fibre Reinforced Self Compacting Concrete(FRSCC) is emerging as improved structural material with enhanced mechanical properties of higher Young’s modulus, increased compressive strength, crack resistance and durability. The present studies are aimed at understanding the effect of mechanical strength properties of FRSCC using glass fibres. In this study anti-crack high dispersion glass fibres with aspect ratio of 857 are used in M30 grade Self Compacting Concrete (SCC) with a dosage of 0.60kg/m3. The stress-strain behaviour of Glass Fibre Reinforced Self Compacting Concrete (GFRSCC) was investigated on standard cylinders of 150mm x 300 mm and mathematical models in the form of polynomial equations were developed. Subsequently, wall panels of 1500mm x 1000 mm size with 75mm thick(t) were cast with the same mix as investigated for mechanical properties. The wall panels were tested under vertical compressive load with minimum eccentricity with top and bottom edges fixed until failure. From the experimental results, it is observed that the ultimate load for GFRSCC wall panel exceeded by 25 % when compared to plain SCC wall panels which clearly indicates the presence of glass fibres causing this increased load carrying capacity.
