Objective: This study aimed to improve and renovate deteriorated sidewalks in the northern region of the country by incorporating nano-fiber cellulose into clay blocks. Given that compressive strength, slip resistance, and water absorption are critical factors for sidewalk pavements in deteriorated areas with low traffic loads, this research investigates the performance of clay blocks stabilized with nano-fiber cellulose for use in paving low-traffic sidewalks in Amreh village. The study also examines the color stability of the treated blocks.
Method: The research method was based on field observations, environmental surveys, and experimental–laboratory analyses.
Results: The results showed that increasing the nano-fiber cellulose content to 10% significantly improved the compressive strength of the samples at all curing ages of 3, 7, and 28 days. However, increasing the nano-fiber cellulose content to 15% reduced this improvement rate. The highest compressive strength was achieved in blocks containing 10% nano-fiber cellulose after 28 days of curing, which showed a 69% increase compared to the control sample of the same age. Furthermore, the compressive strength of all samples increased with curing time. The average surface friction coefficient and water absorption of the samples decreased by approximately 11% and 20%, respectively, when the nano-fiber cellulose content was increased to 15% compared to the control. Moreover, no noticeable color differences were observed in the nano-fiber cellulose–stabilized blocks relative to the control.
Conclusions: The findings indicate that nano-fiber cellulose–stabilized adobe blocks can enhance the performance of adobe pavements and may serve as a viable material for paving sidewalks with low traffic loads in Amreh village.
