A quantitative comparison of real and computer-generated
(model) cement paste microstructures based on the
analysis of three-dimensional image sets is presented.
In addition to a visual presentation of extracted
two-dimensional images, the comparison is based on the
calculation of the normalized two-point correlation
function for a variety of phases including unhydrated
cement, hydration products, and capillary porosity. A
favorable comparison is observed between model and real
microstructures for both the two-dimensional images and
the computed correlation functions. Several interesting
observations from the correlation analysis are
introduced and discussed. This analysis provides one
further validation of the use of microstructure models
to predict the microstructure and properties of
