Water-to-Cement Distance Analysis Software


(Return to Cement Hydration and Degradation Modeling Software)

A menu-based system for computing the water-to-cement distance (proximity) function for user selected values of w/c and cement particle size distribution.

In the given table, enter the particle size distribution of the cement. When the simulation is finished, you can view the water-to-cement distance distribution in your model paste, along with a table indicating the fractional water volume as a function of distance from the cement particle surfaces.
