A detailed description of the use of two-dimensional SEM/X-ray images as a starting point for modelling cement hydration and microstructure development can be found in the original version of this user's guide [4]. The analysis is based on the determination of phase area fractions, surface area fractions, and autocorrelation functions as described previously [4]. Because these programs (statsimp, corrcalc, and corrxy2r) have not changed from their original versions, they will not be further documented in this update.
