Specialised testing facilities and equipment

Multi-axial compression machine for concrete under elevated temperature

Recently constructed at the University of Sheffield, this unique device can deliver three independent principal stresses (up to 400 MPa) on 100 mm cubes.
The precision of the meaurement system enables stresses and strains to be detected to within 0.2 MPa
and 10 microstrain respectively.
