Glass fibre reinforced polymer (GFRP) has proven to be a significant technical breakthrough in concrete reinforcing. Because current technical tools and materials are unable to reduce weight, increase spans, or create slim structures, the search for value composite materials is encouraged. Fiber-reinforced polymer (FRP) materials have risen to prominence as a substitute for steel reinforcing bars in concrete buildings. FRP reinforcing bars have an advantage over steel reinforcement in that they are noncorrosive and nonconductive in some cases. The use of FRP results in attractive performances in a variety of environments, including static, dynamic, and exciting ones. As approaches for using the full FRP strength, minimising brittleness, fire danger, and unintentional damage, reducing energy consumption and carbon emissions during manufacture, and lowering the high initial cost are developed, the acceptability and use of FRPs in reinforcing RC structures will expand. A life cycle cost analysis has been used recently to determine the cost effectiveness of FRP composites as compared with conventional materials. This paper presents simple methods for evaluating comparative life cycle costs for concrete structures made up of conventional and FRP rods.
