Compressed Stabilized Earth Bricks (CSEBs) are produced from a mixture of soil, sand, water, and a stabilizer typically ordinary Portland cement, lime, fly ash, bitumen, or a combination of these materials and then compacting the mixture in a mold. This research article investigates the effects of varying cement stabilizer ratios (5 %, 7 %, and 10 %) on the mechanical properties and water absorption characteristics of compressed stabilized earth bricks. The experimental program included evaluations of dry and wet state compressive strength, flexural tensile strength, total water absorption, and capillary water absorption. The results indicate that increasing the cement content significantly improves the mechanical properties of compressed stabilized earth bricks while reducing their water absorption capacity. When compared with those of tested fired clay bricks and certain international standards for compressed stabilized earth bricks, demonstrated higher performance in these metrics. The findings of this study underscore the potential of compressed stabilized earth bricks as a feasible and advantageous building material for construction in Afghanistan, where leveraging locally available sourced materials can significantly reduce construction costs and minimize environmental impact, supporting the development of affordable and eco-friendly housing solutions
