Permeability and diffusivity of concrete as function of temperature

Tests have been carried out on 11 types of concrete—ranging from normal-strength to high-strength concrete, to polymer-modified and self-compacting concrete—establishing permeability and diffusivity of concrete as a function of temperature between 20 and 80 °C. The results show a considerable increa...

Zusammenfassung:	Tests have been carried out on 11 types of concrete—ranging from normal-strength to high-strength concrete, to polymer-modified and self-compacting concrete—establishing permeability and diffusivity of concrete as a function of temperature between 20 and 80 °C. The results show a considerable increase of these properties with temperature. Theoretical prediction on the basis of thermodynamics shows reasonable to good agreement between theory and experiment.
