The effect of temperature on the mechanical behaviour of geomaterials is relevant in a number of geotechnical applications including low enthalpy energy geostructures. Mechanical response of clays upon heating is not always intuitive, and this includes the volumetric 'collapse' observed in normally consolidates clays. This paper reviews the effect of temperature on clay particle interaction forces (Colombian, van der Waals and mechanical) in the attempt to elucidate the micro-mechanisms underlying temperature-induced behaviour observed at the macroscale.
