The present study aims to investigate the physical, petrological, and mechanical properties of ten different types of rocks in the Indian subcontinent, required for the design of structures built in rocks. A comparative assessment is done for the stress-strain response of all the rocks collected under three main categories, e.g., igneous, sedimentary, and metamorphic. The physical properties, e.g., densities and slake durability indices, are determined. The peterological tests are carried out by scanning electron microscope and the X-ray diffraction technique. Mechanical properties, e.g., hardness, uniaxial compressive strength, elastic modulus, and Poisson’s ratio, of the 10 different types of rocks are obtained through static loading at a strain rate of 0.001/s. Lastly, various correlation equations are proposed relating the uniaxial compressive strength, density, elastic modulus, and hardness of the 10 rocks. And the rocks are classified based on the Deere-Miller rock mass classification system.
