Interest in utilizing industrial waste and by-products in construction materials is growing, given recent concerns about sustainable practices aligning with the principles of the circular economy. Within this context, compressed earth blocks (CEBs) are emerging as an alternative to traditional building materials, offering cost-effectiveness, energy efficiency, and reduced environmental impact. This systematic review comprehensively explores the incorporation of industrial waste and by-products, including construction and demolition waste (CDW), in the production of CEBs. An approach based on the PRISMA model is adopted to analyze the outcomes from primary scientific databases, namely Scopus and Web of Science. The advantages and limitations of incorporating industrial waste and by-products into CEBs are thoroughly discussed. The results show that these waste materials can improve the mechanical, durability, and thermal insulation properties of CEBs. However, careful selection and processing are necessary for compatibility with CEB production. Factors like particle size distribution, chemical composition, and processing techniques significantly influence block performance. This research highlights the potential for more sustainable practices in CEB production while enhancing the mechanical and functional properties of this building product. The findings contribute to advancing knowledge in the field, benefiting researchers, practitioners, and policymakers interested in sustainable construction practices.
