Abstract (300 words maximum)
Steel Fiber Reinforcement is used to improve durability and toughness in concrete. Using steel fiber in production of concrete could eliminate the need for steel reinforcing and has potential to reduce CO2, which is important for producing environmentally friendly concrete. Cracking and fracturing under dynamic load could be prevented with enhancing the durability of concrete. Flexural Strength Capacity of Concrete depends on different variables, such as concrete mixture, compressive strength, cracking… Traditional concrete has flexural strength of 400-700psi (2.76 MPa-4.83 MPa) determined using a 3-point bending test, simulating the loading of the vehicle on the slab. The goal of this project is to produce high quality concrete mixture which could be resistant to dynamic loads. This work presents current progress toward developing concrete mixture design resistant to dynamic loads, which is important for pavement design. A 3-point bending test will be utilized at Kennesaw State University in order to determine the difference between the flexural strength capacity of reinforced concrete and flexural strength capacity of concrete fabricated using Fiber Glass Rebars. Concrete beams with square cross section 6in x 6in and 5ft (15cm x 15cm x 1.67m) length will be cast at Kennesaw State University using the same concrete mixture design and different type of rebars. Deflection of the beams will be measured using dial indicator.
