Abstract—The necessity of metakaolin in steel fibre reinforced concrete to enhance the strength properties of concrete. In the present day construction industry needs of finding effective materials for increasing the strength of concrete structures. Hence an attempt has been made in the present experimental investigations to study the effect of addition of steel fibre at a dosage of 1.5% of the total weight of concrete as fibres. Metakaolin was used at 8% of the total weight of cement as metakaolin, and the addition of steel fibres at 1.5% and 8% of metakaolin. Experimental investigation was done using M40 mix and tests were carried out as per recommended procedures by relevant codes. The results were compared with control concrete it was observed that concrete blocks incorporated with steel fibre increased its compressive strength by 8.91% and tensile strength by 26.94%. Metakaolin and steel fiber blocks exhibited an increase in flexural strength of concrete in 58.28%.
