Mechanical properties of concrete using natural fibres - An overview

Abstract

Currently, due to global warming, a lot of investigation and advance has been growing in the possible use of natural fibres composite universally. Scholars highly initiated the significance due to its advantage of human-made fibres, such as little ecological impact and low cost. Many studies were established to enhance the mechanical execution and uses of natural fibre in the manufacturing trade. Investigation revealed on natural fibre composites can be set into a load-bearing structural and infrastructure use. As an engineered usual material, related to human-made fibre composites, the attributes of natural fibre compounds can be oriented to attain a positive request. The common problems in operational with natural fibre compounds were excessive discrepancy and appearances. Natural fibre composites' attributes, which have a significant level, are mostly subjective by the category of fibres, ecological circumstances also the source of cellulose fibres, and the kind of fiber treatments. As the addition of natural fibre increases in fiber-reinforced concrete production, its slump test value decreases, but it improves the mechanical property of concrete up to a certain value. Then, it starts to decline compared to the control mix design and also, the mode of failure changes from brittle to ductile with the inclusion of natural fiber. Though, cellulose fibre composites might appear as a novel substitute for a rock-solid material with their uniqueness and unevenness and substitute expensive human-made fiber composites. This assessment will deliver an overview of natural fibre mechanical performance and toughness in the concrete, one of the importance of natural fibre compared to a human-made one, and the detailed achievements on its uses supported by the literature.
