Polymer fiber reinforced concrete

Polymer fiber reinforced concrete or PFRC is a composite material which is used for building construction. This is a relatively new material with more efficiency, strength and is inexpensive. Nowadays it is commonly used for the repair of new and deteriorating structures. PFRC responds linear-elastically to axial stress. The response of PFRC to axial compression is dependent on the relative proportion in volume of fibers, the characteristic properties of fiber and resin and the interface bond strength. The failure of PFRC during compression is called fiber buckling. Tensile strength is a main cause of concern in PFRC and is mainly dependent on the fiber material. PFRC is durable and less corrosive. PFRC can be used in bridges, columns, in the repair of new buildings, in the repair of damaged structures, in siding, in cladding, in roofing, in flooring and in partitions. Slurry infiltrated fibrous concrete (SIFCON) is manufactured by infiltrating cement slurry into a bed of preplaced fibers. SIFCON is a high volume fibrous concrete where fiber content varies from 8% to 20%.
