Compressed Stabilized Earth Blocks (CSEBs) offer a sustainable alternative to conventional building materials, yet their strength and durability are critical for widespread adoption. This review paper provides a comparative analysis of cement, lime, and fly ash stabilization effects on CSEB performance. Drawing from established research, we explore stabilization mechanisms, impact of varying stabilizer proportions, and CSEB performance under diverse environmental conditions. Cement stabilization provides rapid strength gain through hydration, forming strong binding agents. Lime enhances long-term strength via pozzolanic reactions, particularly in clayey soils. Fly ash, a pozzolanic material, contributes to durability and utilizes waste resources. The choice of stabilizer depends on soil type, environmental conditions, and project requirements. Our analysis shows that cement offers high early strength, lime improves long-term performance and workability, and fly ash promotes sustainability. Optimal stabilizer proportions are crucial to balance strength gains with potential adverse effects. Compaction and curing conditions significantly influence CSEB performance. This review identifies future research directions, including long-term durability studies under extreme climates, exploration of blended stabilizers and bio-based additives, development of standardized testing protocols, microstructural analysis, and curing condition optimization. These efforts will enhance CSEB performance and promote their adoption as a sustainable building material.
