The strength values are comparable to determinations of uniaxial compressive strength tests of Westerly granite, which range from 130 MPa to 210 MPa (Heard and others, 1974). The slopes of best-fitting lines to the elastic portions of the stress-strain data from the strength experiments were taken for the values of Young's modulus.

Stone Testing

since the strength may vary when the stone is wet, the strength tests (i.e. compressive strength, flexural strength, modulus of rupture) are sometimes performed using wet stone specimens. For the dry condition, the stone specimens are dried in an oven at 60°C ±2°C (140°F ±2°F) for at least 48 hours or
