Abstract

This study investigates the geomechanical properties of sandstone from the southern part of Isfahan city using the Cerchar Abrasivity Index (CAI), Unconfined Compressive Strength (UCS), and point load tests. Twelve sandstone samples were analyzed to evaluate their abrasiveness and mechanical strength. The CAI value was determined to be 3.55, indicating a moderately high level of abrasiveness. The UCS test revealed strength of 35 MPa, and the estimated Hardness Rating (HR) was 25.6. These findings offer critical insights into the material properties of Isfahan’s sandstone, which are essential for construction and excavation projects in the region. The results provide a useful framework for predicting tool wear and rock behavior during engineering operations.
