Abstract:
The Virtual Cement and Concrete Testing Laboratory
(VCCTL) consortium was formed in January of 2001.
Headquartered in the Building and Fire Research
Laboratory at the National Institute of Standards and
Technology (NIST), the consortium currently consists of
NIST and six industrial members: Cemex, Dyckerhoff
Zement GmbH, Holcim Inc., Master Builders Technologies,
the Portland Cement Association, and W.R. Grace & Co.-
Conn. The overall goals of the consortium are to develop
a virtual testing system to reduce the amount of
physical concrete testing and expedite the research and
development process. This will result in substantial
time and cost savings to the concrete construction
industry as a whole. The three major initial research
topics of the consortium are: 1) enhancements to the
cement hydration and microstructure development model to
consider additional supplementary materials such as
slags and limestone and the prediction of pore solution
concentrations, 2) computation of the elastic properties
of three-dimensional microstructures, and 3)
experimental measurement and computer modeling of the
rheological properties of cement-based materials.
Progress made during the first year in each of these
three areas is presented in this report.
