In this paper, experimental and computer modelling studies of the effects of curing on hydration are presented. Degree of hydration has been quantified for saturated, sealed, and 90% relative humidity ambient environments, all at 25ºC. For both the saturated and the sealed curing conditions, experimental results for degree of hydration and scanning electron microscopy images are compared to those generated using the NIST cement paste microstructural model. Implications for the field curing of concrete are also addressed.
