Abstract
It’s a structural behavior research was done on normal concrete because it possesses low tensile
strength shows cracking. The addition of fiber can enhance the compressive and tensile properties of
concrete. An experimental study was conducted to evaluate the compressive and tensile strength of
fiber-reinforced concrete, confirming the improvements in these mechanical properties. The various
aspects covered are compression test, split tensile strength, Effects of fibers on concrete. The study is
done on the comparison between nominal concrete and fiber reinforced concrete for that purpose
steel fiber is used as reinforcement as it has several characteristics other than any fiber. The test is
performed for m25 grade of concrete 12 cubes and 12 cylinders have been cast in which 6 are of
normal and other of steel fibers in the Specimens with fiber percentages of 0.9%, 1.2%, and 1.5%
were tested for compressive strength and split tensile strength at intervals of 3, 7, and 28 days after
casting. The results of the test shows steel fiber reinforced concrete showing better strength in both
compression and tension than nominal concrete there is increase in the strength as increase in the
dosage of steel fibers. After 28 days of test it is been clear that Fibers can be used as reinforcement
with normal concrete.
