Building structures would be impossible without concrete, which is the world’s most commonly used construction material after water. Resources, recycling, durability, and environmental quality are just a few of the many areas of concrete production that have seen advancements. The use of natural fibers in concrete is one of these methods. Plant-based materials derived from natural fibers are readily available, low-cost renewable resources. In this study, the use of natural fiber from the Phragmites-Australis plant (PA) has been investigated. The effect of incorporating PA in different volume percentages (0 to 2%) on the chemical shrinkage and mechanical properties of mortar has been examined. In this experiment, the PA stems were cut into pieces 1 cm long and 2 cm wide and treated with 4% sodium hydroxide solution (NaOH). The w/c was kept constant for all mixes. Mortar samples were tested for 28 days. Testing involved chemical shrinkage, density, ultra-pulse velocity (UPV), and compressive and flexural strengths. Results showed that the addition of PA reduced the chemical shrinkage of mortars. The addition of 1% PA increased the UPV, compressive strength, and flexural strength of mortar samples. Furthermore, a strong correlation was found between chemical shrinkage and compressive strength, indicating that as the pozzolanic reaction progressed, the chemical shrinkage increased. Therefore, the inclusion of PA plant as an eco-friendly material in mortar mixtures contributes to a sustainable building.
