Abstract
Uniaxial compression tests were conducted on pink granite core specimens to explore the possibility of water-weakening of the rock. Tests were performed at a stress rate of 0.75 MPa/s and at room temperature. The water-saturated specimens were observed to display a slightly lower peak strength and strength at the onset of stable crack growth, compared with dry specimens. However, water saturation appeared to have no effect on the strength at the onset of unstable crack growth, tangent Young's modulus and Poisson's ratio. The effects of loading rate and temperature should be investigated in any further study on the water-weakening trend of the granite.
