Research Brief: Modeling the Freeze-Thaw Damage Mechanism in Cement
(2019-01)
Freeze-thaw (FT) damage is a significant threat to roads and pavement, yet the underlying mechanism is still unclear. Conventional thinking attributes the damage to pressure generated by expansion of water upon freezing. ...
Research Brief: Capillary Stress During Cement Drying Shrinkage
