The growth of Self Compacting Concrete is revolutionary landmark in the history of construction industry resulting in predominant usage of SCC worldwide nowadays. It has many advantages over normal concrete in terms of enhancement in productivity, reduction in labour and overall cost, excellent finished product with excell ent mechanical response and durability. Incorporation of fibres further enhances its properties specially related to post crack behavior of SCC. Hence the aim of the present work is to make a comparative study of mechanical properties of self consolidating concrete, reinforced with glass fibres. The variables involve in the study are type and different percentage of fibres. The basic properties of fresh SCC and mechanical properties, toughness, fracture energy were studied. Microstructure study of various m ixes is done through scanning electron microscope to study the hydrated structure and bond development between fiber and mix. The primary aim of this study is to explore the acceptability of demolished concrete waste aggregate to make self compacting concr ete of high strength and desirable properties. The compressive strength of all the concrete mixes were measured at the age of 7 and 28 days, and testing them for, water absorption, sulfate resistance.
