This document serves as the user's manual for Version
1.1 of the Virtual Cement and Concrete Testing
Laboratory (VCCTL). Using the VCCTL, a user may create
starting microstructures of cement (gypsum, fly ash,
etc.) particles in water, hydrate the microstructures
under controlled curing conditions, leach the
portlandite and remaining cement clinker phases from
hydrated microstructures, subject hydrated
microstructures to attack by sulfate solutions, view
images and animations of 3-D microstructures, and/or
evaluate a variety of properties of hydrated/leached
microstructures for direct comparison to experimental
data. The VCCTL includes a web-based interface that
provides a menu-driven system of forms for obtaining
user input and returning results.
