A Comparative Study of the Experimental Investigation of different types of fibres used in Concrete

Different types of fibres used in concrete have received much attention in civil engineering in recent years, mainly because they improve the low tensile strength and shrinkage cracks of concrete. However, there are still many problems in the research results on different types of Fibers. For example, there is still debate about the performance-enhancing or detrimental effects of different types of fibres in concrete. There is also a dispute about the influence of the size, strength, elastic modulus and other characteristic parameters of each fibre on the properties of the substrate. Research on fibre mixing rules of hybrid fibre reinforced concrete (HFRC) is incomplete. There is controversy regarding the choice of fibres for hybrid yarns as well as the characterization of the hybrid effect. In summary, it is necessary to review, synthesize and compare current research on FRC. Based on the major research achievements on FRC in recent years, this article synthesizes and evaluates existing research in experimental research and theoretical research on different types of fibre materials, aiming to create Reference conditions for researchers in the same field. Finally, combined with research experience in related fields, new perspectives and proposals on FRC’s research are proposed for research and application. This research paper is mainly focus on the different fibres (glass, cotton, steel).
