    Abstract :

    Concrete is the most broadly utilized construction material in structural building because of its high structural strength and stability, using strength and high performance concrete has been expanding all through the world. Among the different techniques used to improve the strength and performance of concrete, utilization of Cement Replacement Material (CRM) like Meta-kaolin is a generally new approach. The understanding of fracture mechanism of reinforced concrete (RC) structure is vital and under this study its focusing to crack and deflection behavior for RC beam under static loading.An experimental investigation has been carried out on 7-RC beam to investigate the behavior of reinforced concrete beams with 10% of Nano-Metakaolin in flexural to study effect of utilizing Nano-Metakaolin, effect of flexural reinforcement ratios, effect of compression reinforcement ratios and effect of characteristic strength of concrete. It is found that partial replacement of cement with Nano -Metakaolin has a greater influence on the tested beams by 122,107,107&125% for initial crack, ultimate load, maximum defection and toughness, with minimum flexural reinforcement ratio 1.29%, and minimum compression reinforcement ratio 0.44.
