Abstract

ABSTRACT: This review article focused on the mechanical properties of sisal, coir and hemp fiber-reinforced concrete composites and several factors affecting the mechanical properties of natural fiber-reinforced concrete (NFRC) composites. Several treatments were applied to improve the surface of natural fiber for improving the strength and durability of composites. Recently researchers have investigated the mechanical properties by using NaOH treatments effects of sisal, coir and hemp fibers-reinforced concrete composite are highlighted in this study. A variety of recent studies showed that sodium hydroxide (NaOH) treatment plays a significant role in the adhesion of fiber concrete composites. It was found that NaOH improves the mechanical properties of the natural fiber-reinforced composites. Further, the treatment techniques for the modification of these natural fibers by improving the surface of these natural fibers are discussed. In the same way, previous research has investigated the effect of thermal stability and water absorption on the mechanical properties. Generally, this review article was aimed to highlight, gather, and explore the previous reported research studies leading the mechanical properties of sisal, coir and hemp fiber and its polymer composites to deliver a basis source of data and literature to expose it as composite materials like synthetic fibers.
