The durability of a building stone is its resistance to deterioration processes under the climatic conditions of a given geographical area. This parameter plays an important role in the selection of a suitable building stone, as ignoring it can lead to premature deterioration of the stone during the life of a building. Therefore, before selecting a building stone, it is necessary to pay special attention to its durability and to select a stone that has a suitable resistance to environmental degradation processes. The physical and strength characteristics are among the factors that influence the durability of a building stone. The evaluation of these characteristics can provide valuable information about the durability of stone subjected to deterioration processes. In this work, the effects of physical and strength characteristics on the durability of building stones were investigated. The results indicate that porosity, water content, degree of saturation and pore size distribution are the most important physical characteristics determining the durability of a building stone. In addition, strength properties, including uniaxial compressive strength, tensile strength, flexural strength and abrasion resistance, also play an important role in the durability of a building stone. The results of the present study can be used as a simple, quick, inexpensive and practical tool to indirectly evaluate the durability of building stone against environmental degradation processes.
