Abstract: Experimental investigation is carried out to study the behavior of Metakaolin reinforced concrete in comparison to fly ash reinforced concrete with and without steel fibers on compressive strength and under shear strength. The weakness in tension of conventional concrete is overcome by incorporating steel fibers into the matrix while the Metakaolin and Fly ash can increase many properties of concrete and also reduces the cementing consumption. 12 beams of length 1500mm, breadth 150mm and depth 200mm having 4-12mm diameter bars as tension reinforcement and 2L, 8mm diameter bars spaced at 130mm c/c as stirrups were casted and cured for 28 days and tested under two point loading applied at 1/3 span points.
