A poromechanics model for plastic shrinkage of fresh cementitious materials

When fresh cementitious materials are exposed to evaporation, drying of the pore fluid leads to capillary pressure development and plastic shrinkage. Plastic shrinkage occurring after the solid percolation threshold plays an important role in the initiation and propagation of plastic shrinkage cracks, which may compromise the durability and decrease the service life of concrete structures. In this study, a poromechanics approach to plastic...
