This NISTIR serves as the user's manual for Version 1.0
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, 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.
Two example applications of using the VCCTL to study
specific scenarios of interest to the cement-based
materials research community are also presented.
