During cement production, work has been conducted to examine the effect of metakaolin (MK) substitution with cement strength due to associated environmental pollution and to preserve virgin raw materials for future generations, and yet at the same time, utilizing the approachability of additional cementing materials such as metakaolin-an engineered material. In this study, the strength characteristics of Metakaolin concrete with and without crimped steel fiber have been tested. Reinforced concrete with short random fibers has been identified by monitoring the origin length/dia. propagation of fractures to enhance the strength of cementitious matrices. Steel fibers have contributed to mechanical qualities by minimizing the crack development inside concrete blocks and so improving concrete strength at all testing ages. Results show that the flexural strength of M60 concrete increases with 1.5 percentages of fiber content and strength-effectiveness at aspect ratio 60 is observed to be maximum.
