Despite being the most widely used building material in the world, traditional reinforced concrete has to be updated due to its brittle failure mechanism under stress. Concrete is combined with short steel fibres to bring back its brittleness. This study examines the flexural behaviour of RC beams and determines the optimal ratio of steel fibre insertion. Hooked end steel fibres with a diameter of 0.75 mm and a length of 50 mm are included into reinforced concrete beams to achieve the required concrete compressive strength of 30 MPa (M30). Steel fibres added to the concrete mix at the following percentages: zero, seventy-five hundredths of a percent, one percent, one and a quarter of a percent, and one and a half of a percent were tested on fifteen cubes, fifteen cylinders, and fifteen beams. 700 mm is the length, 150 mm is the width, and 150 mm is the depth of the beam. The flexural behaviour of reinforced concrete beams with steel fibre additions was compared to ordinary (or conventional) reinforced beams without steel fibres using a third-point loading test apparatus made for M30 concrete. The ideal ratio of steel fibres, hooked-end steel fibres, and flexural behavior/flexural strength are all important
