Qualified adobe products need to be produced due to decreasing sources of proper raw materials and the need for affordable and sustainable construction. Within the scope of developing the qualified adobe products, the study covers two main aims: “Developing a practical Nano-clay enrichment method in the laboratory to increase the Nano-clay in the clay content of adobe soil” and “developing qualified adobe products having enriched Nano-clay content”. The proper soil samples were selected according to their potential for Nano-clay enrichment and adobe production. The clay type is a crucial parameter for Nano-clay enrichment by ultrasonic treatment. The soils rich in montmorillonite were more suitable for Nano-clay enrichment than those rich in illite, kaolinite and chlorite. Nano-clay enriched qualified adobe was achieved by having improved compressive and flexural strengths which are higher than the requirements of the regulations/codes while keeping their inherent breathable and capillary water absorption features. Total Nano-clay contents and pozzolanic characteristics of the treated adobe products were the main factors affecting the compressive and flexural strengths, respectively. In addition, the use of Nano-sized calcium oxide additive was effective in treated adobe products including montmorillonite as the main clay. Effective use of soil resources not appropriate for adobe production was provided by Nano-clay enrichment by ultrasonic treatment. In addition to its contribution to the fields of innovative adobe construction industry and archaeology, the Nano-clay enrichment treatment in adobe soil can be practically applied in rural areas by teaching the local people the soil resource selection and the treatment process.
