This document presents the results of an experimental study investigating the strength and water permeation properties of rice husk ash concrete reinforced with polypropylene fibers. Thirteen concrete mixes were prepared by partially replacing cement with rice husk ash at 10%, 15%, and 20% and adding polypropylene fibers at 0.5%, 0.75%, and 1% by weight. The compressive, splitting tensile, and flexural strengths as well as water absorption were tested at various curing ages. The results showed that compressive strength initially increased at 10% rice husk ash replacement but decreased at higher replacements, while fiber addition increased strength up to 0.5% fiber content. Both rice husk ash and fibers reduced
