FIBERGLASS BARS, AN INNOVATIVE ALTERNATIVE AND ITS POTENTIAL: LITERATURE REVIEW

Abstract

The performance, efficiency, resilience and sustainability of a structure are fundamental parameters to promote the quality of life and economic development of an infrastructure. Currently, pathologies such as corrosion are serious problems that burden public coffers and the final consumer, in addition to generating greater annoyances over time. Therefore, the use of alternative and high-performance materials is gaining more and more attention, due to the high complexity of management, maintenance and resilient adaptation to social and climatic changes, accentuated pollution, decreased financial resources and among others throughout its cycle infrastructure life. Therefore, GFRP (Glass-Fiber-Reinforced Polymer) bars gain evidence for being corrosive inert, being used as a tool for repair, maintenance and employment in new civil works. This technology-associated material enables cost reduction and improvement in the structure's behavior. The background of this article is to encourage future studies, aiming to develop a Brazilian standard for sizing reinforced concrete (CA) GFRP. The mastery of this subject to professionals, managers and those involved in the design and implementation of infrastructure systems and civil works is essential, as it allows for systemic planning, optimized and consistent with needs, minimizing costs, but without compromising the quality of the structure.
