Abstract: Concrete members reinforced with glass fiber-reinforced polymer (GFRP) bars exhibit large deflections and crack widths compared with concrete members reinforced with steel. However, glass fibers are cheaper, more flexible, and lighter than their carbon counterpart, making it an ideal reinforcing agent for many polymer products. GFRP reinforcement bars produced this way can be made in a variety of diameters, shapes and tensile strengths. Fibre-reinforced plastic (FRP) (also called fiber-reinforced polymer, or fiber-reinforced plastic) is a composite material made of a polymer matrix reinforced with fibres.The fibres are usually glass (in fibreglass), carbon (in carbon-fiber-reinforced polymer), aramid, or basalt.Rarely, other fibres such as paper, wood, or asbestos have been used. 1.1 This specification covers glass fiber reinforced polymer (GFRP) bars, provided in cut lengths and bent shapes and having an external surface enhancement for concrete reinforcement. Glass fiber reinforced polymer bars have potential application in the seawater sea sand concrete. Fibreglass is an excellent example of a relatively modern composite material (Invented in 1938 by Russel Games). It may be in the form of roving’s, chopped strand, yarns, fabrics and mats. Abstract. We put it in our footings, foundations, stem walls and slabs, and we also put it in our building envelopes. It has high electrical insulating properties, good heat resistance, and has the lowest cost. The mix is heated until it melts at about 1260°C.
