The durability of a building stone is its resistance against deterioration processes under the climatic conditions in a given geographical area. This parameter plays a significant role in selecting a suitable building stone so that ignoring it can lead to premature deterioration of the stone during the service 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 durability against environmental deterioration processes. The physical and strength characteristics are among the factors affecting the durability of a building stone. Evaluations of these characteristics can provide valuable information regarding the durability of stone subjected to deterioration processes. In this work, the effects of physical and strength characteristics on the durability of the building stones were investigated. The results indicate that the porosity, water content, saturation degree, and pore size distribution are the most significant physical characteristics determining the durability of a building stone. In addition, strength characteristics, including strengths of the uniaxial compressive, Brazilian tensile, flexural, and abrasion strengths, also play a prominent role in the durability of a building stone. The findings of the present study can be used as a simple, rapid, low-cost, and practical tool for indirectly evaluating the durability of building stone against environmental deterioration processes.
