Avaliação do comportamento mecânico de fibras vegetais e sintéticas utilizadas em materiais compósitos cimentícios

Abstract

Considering the economic, social and environmental aspects, several studies have been carried out on the potential advantages of using natural and synthetic fibers in concrete. The use of natural and synthetic fibers can produce favorable results, since their presence demonstrates substantial advantages in terms of mechanical properties of the composite material. In this scenario, this work aims to investigate the resistance of concrete reinforced with natural and synthetic fibers as well as the advantages provided by the addition of fibers to the cement composite. After the investigation, it can be concluded that most researchers reported that the mechanical performance of concrete increased by up to 41.3% with the addition of fibers. However, the exaggerated fiber content generates a decrease in mechanical performance due to the lack of workability and the increase of voids inside the concrete. The incorporation of fibers in concrete can minimize environmental problems and also promote environmentally friendly and long-term solutions that are effective in the construction industry.
