Fiber reinforced concrete is the most widely using technology since early days. It is a technique of adding single type fiber or a blend of fiber to the mixture of concrete. Steel fibers and synthetic fibers can be added to the mixture which adds the mechanical properties of concrete. Concrete which is compared to other building structure is more brittle and it has poor tensile strength. As concrete is subjected to cracks, fibers are adding to it to get the strength. Mostly used fibers for reinforcement are natural fibers, synthetic fibers, steel fibers and glass fibers.
Advantages of Fiber Reinforced Concrete
· It controls cracking of concrete
· Reduce permeability of concrete and thus reduce water bleeding
· Higher the modulus elasticity of the fiber, higher will be the loading capacity of material.
Fiber Reinforced composites
Fiber reinforced composites consists of fibers and a matrix. Fibers are the main source of strength. And the matrix is used to bind fibers together in shape and transfers stresses between the fibers. It protects fibers from mechanical as well as external damages.
