Green-reinforced Sedimentary Silt with Natural Curaua Fiber

Journal of Natural Fibers, 2022
Lime and cement as traditional binders need to be reduced in soil stabilization to avoid carbon dioxide emissions. Infrastructure development like paved structures, buildings, foundations, and dams involves exhaustive use of natural resources and serious concern for the environment.
