Description
The exponential growth in urban as well as industrial development has led to growing interest in waste management and utilizing industrial byproducts. The palmyra fiber is an abundantly available fiber extracted from the palmyra palm tree whose potential as reinforcing material is less explored. This study investigates the influence of alkali treated palmyra fibers on the strength and durability properties of binary blended concrete with 80% cement and 20% ground granulated blast-furnace slag. The alkali treated palmyra fibers of 50mm length were added in three different proportions of 0.5%, 1% and 1.5% by mass of binder materials to produce M30 grade of concrete. The workability of binary blended concrete was reduced with the addition of alkali treated palmyra fibers. Comprehensive investigations were carried out on both mechanical (compressive, split tensile, and flexural strength) and durability properties (sorptivity, resistance to sulphate and acid attack). Additionally, the performance under impact loading was also evaluated. The results reveal that compressive strength nominally reduced by 312% with the addition of fibers, while tensile strength and flexural strength increased with every increment in fiber content. The inclusion of palmyra fibers considerably increased impact resistance, ranging from 300 to 600% compared to conventional concrete. Also, palmyra fiber reinforced concrete exhibited better resistance to sulphate attack. Springer Nature Switzerland AG 2025.
