Abstract

 In this research the relationships between petrological properties and physical and mechanical characteristics have been investigated in three different granitoid rocks. According to field investigations granitoid with coarse, medium and fine texture from three regions respectively Golpaigan (Hassn Robat), Aligudarz (Pirtak) and Borujerd (Tavandasht) were selected and sampled. Laboratory studies on these samples and their thin sections determined mineralogical and petrological composition. According to testes results some of the physical properties such as porosity and density, and some of the mechanical properties such as point load strength and uniaxial compressive strength were determined. Then relationship between physical and mechanical properties with petrological characterizes have been studied. This research showed that in these granitoid rocks the effect of the texture type on physical and mechanical properties is greater than mineralogical composition. Also findings showed that the investigation on petrological properties as primary index for evaluation of physical and mechanical properties of granitoid rocks could be used.
