The study is undertaken to find the combined effect of 16% metakaolin (MK) along with steel fiber reinforcement (SFR) on M40 grade of concrete with Portland pozzolana cement (PPC). For this purpose steel fiber of aspect ratio (l/d) as 41.67 and 81.33 were used. Cubes, cylinders and prisms were casted by using different eight concrete mixtures using 0.5% 1% and 1.5% steel fibers by volume of concrete. At 28 days of water curing these casted specimens were subjected to tests like compressive strength, split tensile strength, flexural strength and ultrasonic pulse speed test. It was located that metallic fiber along with metakaolin mixture has significantly stepped forward these properties. Regression analysis on experimental results generated some statistical model predicting the results in good agreement.
