The Virtual Cement and Concrete Testing Laboratory Consortium Annual Report 2001



Dale P. Bentz


The Virtual Cement and Concrete Testing Laboratory(VCCTL) consortium was formed in January of 2001. Headquartered in the Building and Fire ResearchLaboratory at the National Institute of Standardsand Technology (NIST), the consortium currentlyconsists of NIST and six industrial members:Cemex, Dyckerhoff Zement GmbH, Holcim Inc., MasterBuilders Technologies, the Portland CementAssociation, and W.R. Grace & Co.- Conn. Theoverall goals of the consortium are to developa virtual testing system to reduce the amount ofphysical 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.
