Abstract

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