Review Natural fibres as construction materials*

This paper reviews the properties of different natural fibres. These natural fibres were investigated by different researchers as a construction material to be used in composites (such as cement paste, mortar and/or concrete). The different researches carried out and the conclusions drawn are briefly presented. The aim of this review is to compile the available data of different natural fibres evaluated in last few decades, and thus, it can be used as a reference/guideline for the upcoming research of a particular fibre. Natural fibres are used to increase the strength properties of the composites. But all properties cannot be improved at the same time because fibres have their own characteristics. So it is recommended that appropriate fibre should be used for a particular purpose. Also, there should be guideline/criteria for acceptance of natural fibres, because of variable properties of a particular fibre in different regions. No doubt, natural fibres can be used in a variety of manners, but still, there is a need of research for investigating the further properties of fibres
