Creep and shrinkage behavior of carbon fiber reinforced composites: a review

Considering the relevance of the creep and shrinkage phenomena of concrete, this study aims to develop a literature review on these two behaviors in composites reinforced with carbon fibers. A search was performed in the Web of Science and Scopus databaseswith specific combinations of keywords. The selection was based on the most relevant studies of each theme, prioritizing the mechanical property of creep. Based on the studies presented, it was identified that carbon fiber significantly influences the ability to restrict creep and shrinkage of concrete. Another point observed in the study is that fibers with a higher modulus of elasticity than plain concrete canresist creep, unlike fibers with a lower modulus, even in creep tests with pre-cracked concrete. Although there are several studies, there is still not a complete understanding of the subject. The creep and shrinkage behavior can be explored in composites reinforced with carbon fibers when exposed to high temperatures, in ultra-high-performanceconcretes, in post-cracking of structural elements, among others.
