Fiber Reinforced Concrete full report - jolly16 - 08-17-2017 [attachment=14054] What is a Fiber ? Small piece of reinforcing material possessing certain characteristic properties. Can be circular or flat. Parameter used to describe fiber Aspect ratio . Aspect ratio is ratio of its length to its diameter. Typical aspect ratio for fibers ranges from 30 to 150. Concrete (FRC)? Fiber reinforced concrete (FRC) is concrete containing fibrous material which increases its structural integrity. It contains short discrete fibers that are uniformly distributed and randomly oriented. Fibers include steel fibers, glass fibers, synthetic fibers and natural fibers. Within these different fibers that character of fiber reinforced concrete changes with varying concretes, fiber materials, geometries, distribution, orientation and densities History of FRC The concept of using fibers as reinforcement is not new. Fibers have been used as reinforcement since ancient times. Historically, horsehair was used in mortar and straw in mud bricks. In the early 1900s, asbestos fibers were used in concrete, and in the 1950s the concept of composite materials came into being. There was a need to find a replacement for the asbestos used in concrete and other building materials due to the health risks associated with the substance were discovered. By the 1960s, steel, glass (GFRC), and synthetic fibers such as polypropylene fibers were used in concrete, and research into new fiber reinforced concretes continues today.
