The drying shrinkage of hardened Portland cement pastes with watercement ratio from 0.25 to 0.70 was characterized in terms of shrinkage eigenstress determined by thermomechanical analysis (TMA). The eigenstress development with water loss during thermal drying was investigated using thermogravimetr
In this paper the authors tried to analyze their drying shrinkage data in terms of the Munich model. They have attributed the shrinkage below 40% RH to a change in the surface free energy (socalled Bangham shrinkage) and the shrinkage above 40% RH to the disjoining pressure. As the authors are propo
