Abstract

A novel triaxial-torsional testing machine with temperature control has been designed, built, and rendered operational at the Center for Concrete and Geomaterials at Northwestern University. The technical features and capabilities of the machine are described. With a test cavity of diameter 216mm (8.5 in), the machine can handle large specimens. The maximum axial load is 5·MN (1.13 × 10⁶ lb.), and the maximum torque is 5.6 kNm (50,000 in.-lb.). The temperature range is from room to 600°C (1110° F). The test chamber can be filled with gas or water with maximum pressure 138 MPa (20,000 psi), and the specimens can be either sealed or unsealed. The machine opens new horizons in testing the constitutive and fracture properties of concrete and rock.
