Mechanical and Durability Performance of Sisal, Jute, and Hemp Fiber-Reinforced Concrete: Effects of Chemical Treatment and Fiber Geometry (2025)

ABSTRACT This study investigates the influence of three natural fibers – sisal, jute, and hemp – on the mechanical and durability properties of concrete, using a Taguchi L9 orthogonal array to systematically vary fiber type, content (5–15% by weight), length (5–15 mm), and chemical treatment (untrea
