Abstract The purpose of this experimental research was to establish optimal compositions for adobe-brick masonry, masonry mortar and plaster, such as the identification of treatments applied to the clay surface to improve its water resistance. The maximum values of mechanical resistances are obtained for mixture with clay, sand, and a solution of bones glue, flexural tensile strength is improved by adding hemp fibers. The thermal conductivity is improved by adding straw. The optimal mixture for mortar is clay and sand with grains of a maximum size 0-2 mm, admixed with lime. The surface treatment identified is by impregnation with linseed oil.
