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 25 deg C. 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.
