Abstract:
Creep, shrinkage and delayed thermal dilatation of concrete at low stress are caused by mass transport of water and other molecules along thin layers in the microstructures. The theory of the consitutive equation based on this mechanism is summarized and, as an example, a plausible explanation of the phenomenon of drying creep is presented.
