Glass fiber reinforced concrete (GFRC) consists of high strength glass fiber embedded in a cementitious matrix.[1] In this form, both fibers and matrix retain their physical and chemical identities, while offering a synergism: a combination of properties that can not be achieved with either of the components acting alone. In general, fibers are the principal load-carrying members, while the surrounding matrix keeps them in the desired locations and orientation, acting as a load transfer medium between them, and protects them from environmental damage. In fact, the fibers provide reinforcement for the matrix and other useful functions in fiber-reinforced composite materials. Glass fibers can be incorporated into a matrix either in continuous lengths or in discontinuous (chopped) lengths.
