Abstract: The physico-mechanical properties of rocks are important input parameters for designing of mining and civil engineering construction projects. The presence of acidic water in excavated areas ┬Ěpose serious problem and makes the excavation process more difficult. In the present study, sandstone rock specimens were tested in the laboratory in dry, wet and acidic environment. The uniaxial compressive, tensile, shear strength, cohesion and angle of internal friction were determined in acidic water conditions. This study reveals that the acidic water changes the behaviour and strength of rock. The strength decreases linearly from neutral pH to acidic condition. The angle of internal friction increases with decreasing pH values.
