“…Similarly, Taallah et al [37] take a similar stance, suggesting that the addition of fibers may reduce compressive strength. However, this notion needs to be qualified in light of the work by Alene et al [73] and Labiad et al [80]. These studies present graphs illustrating that compressive strength increases with the percentage of fibers used (Figures 16 and 17).…”

“…In the case of CEBs or CSEBs, the values follow a linear progression as a function of thermal conductivity. For example, the mass heat capacity varies from 1704 to 1040 J•kg −1 •k −1 while the thermal conductivity varies from 0.48 to 0.75 W•m −1 •k −1 [32,36,80,86]. These results suggest that incorporating natural fibers or biological binders (powder) improves the thermal performance of adobe or compressed earth blocks (Figure 14).…”

This comprehensive literature review investigates the impact of stabilization and reinforcement techniques on the mechanical, hygrothermal properties, and durability of adobe and compressed earth blocks (CEBs). Recent advancements in understanding these properties have spurred a burgeoning body of research, prompting a meticulous analysis of 70 journal articles and conference proceedings. The selection criteria focused on key parameters including construction method (block type), incorporation of natural fibers or powders, partial or complete cement replacement, pressing techniques, and block preparation methods (adobe or CEB). The findings unearth several significant trends. Foremost, there is a prevailing interest in utilizing waste materials, such as plant matter, construction and demolition waste, and mining by-products, to fortify or stabilize earth blocks. Additionally, the incorporation of natural fibers manifests in a discernible reduction in crack size attributable to shrinkage, accompanied by enhancements in durability, mechanical strength, and thermal resistance. Moreover, this review underscores the imperative of methodological coherence among researchers to facilitate scalable and transposable results. Challenges emerge from the variability in base soil granulometry and disparate research standards, necessitating concerted efforts to harness findings effectively. Furthermore, this review illuminates a gap in complete lifecycle analyses of earthen structures, underscoring the critical necessity for further research to address this shortfall. It emphasizes the urgent need for deeper exploration of properties and sustainability indicators, recognizing the inherent potential and enduring relevance of earthen materials in fostering sustainable development. This synthesis significantly contributes to the advancement of knowledge in the field and underscores the continued importance of earth-based construction methodologies in contemporary sustainable practices.
