Steel Fiber Reinforced Concrete: Mechanical Properties of Concrete

Concrete is relatively brittle, and its tensile strength is typically only about one tenths of its compressive strength. Regular concrete is therefore normally reinforced with steel reinforcing bars. Their main purpose is to increase the energy absorption capacity and toughness of the material, but it also increase tensile and flexural strength of concrete. Concrete containing a hydraulic cement, water, fine or fine and coarse aggregate and discontinuous discrete fibers is called fiber-reinforced concrete (FRC). In this book, critical investigation for M-20 and M25 grade of concrete to study the compressive strength and tensile strength of Hooked end steel fiber reinforced concrete (SFRC) containing fibers of 0%, 0. 5%, 1.0% and 1.5% volume fraction of Hooked end steel fibers of 35mm length and 0.65mm diameter are used. For compression test, the cube and Cylinders are used. For splitting Test, Cylinders are used. The results of tests have been analyzed and compared with a controlled specimen (0% fiber) of concrete.
