Multi-axial Compression of Concrete at Elevated Temperature

mac2T is Sheffield´s unique test facility for Multi-Axial Compression of Concrete at Elevated Temperature, developed to fill the existing gap in high quality experimental data needed for the development of advanced material models for simulating the behaviour of structural concrete under true multiaxial compression at both ambient and elevated temperature.
