Abstract: Rock is used as a basic construction material, and hence, its strength plays a pivotal role in the construction of almost every engineering structure. The determination of physicomechanical properties of rocks is of utmost importance in almost every geotechnical structure. In this study physicomechanical characteristics like unit weight, point load index test (Is(50)/MPa), Schmidt rebound hardness test (S_rh), and uniaxial compressive strength (UCS) were evaluated to correlate these properties with the textural coefficient. For this objective, six kinds of different rocks were studied microscopically, and complete laboratory tests were conducted in the same manner as devised by ASTM and ISRM standards. The microscopic studies were carried out after making thin sections and then the textural characteristics were evaluated. The microfabric texture of rocks alters these properties. The physicomechanical properties were correlated with the textural coefficient via simple regression analysis and the different equations attained show a good relationship between them.

Keywords: digital photographs; textural coefficient; TC; thin sections; uniaxial compressive strength; UCS; Schmidt rebound hardness; SRH; India.
