Abstract

The main purpose of this research was to assess the engineering geological properties of Qom formationlimestones in the east and north-east Hamedan. To this end, 100 samples of limestone were selected from the East and North-East Hamedan and the relationships between petrographic characteristics, physical and mechanical properties were investigated. Index properties such as porosity, dry unit weight, schmit hammer value, point load strength and slake durability index were determined. The petrographic characteristics of the studied rocks such as texture, mineral composition and microstructure were analyzed in thin sections and their intrinsic influence on the physical properties such porosity, mechanical properties such as strength and solubility were also investigated. Microscopic studies on the limestones revealed, that according to Dunham classification, they were grainstone, packstone, wackestone and calcarenite.
