In this study, the physical (specific gravity, weight per unit of volume, capillary water absorption, porosity, freezing-thawing durability and wear), thermal (heat conduction coefficient of solids)) and mechanical (compressive strength and tensile splitting strength) properties of available blend bricks which are traditionally hand produced in Traditional Kastamonu Houses have been examined. Also SEM and BET images were taken to determine the structural characterization of the blend bricks The study started with supply of samples from the Traditional Kastamonu House located in the city center of Kastamonu. Firstly physical and mechanical experiments were applied to the available samples, then to the samples produced by the fabrication method. After the test procedure was completed, the values found were compared. According to the obtained data, it was determined that the available sample has higher specific gravity, weight per unit of volume and heat transfer coefficient values of solid bodies than the fabricated sample. When the values of capillary water absorption, freezethaw effect, porosity, abrasion and compressive strength are taken into consideration, It has been revealed that the bricks produced by the fabrication method are superior to the bricks.
