Headquartered in the Building and Fire Research Laboratory (BFRL) at the National Institute of Standards and Technology (NIST), the consortium currently consists of two NIST laboratories, BFRL and the Information Technology Laboratory (ITL), and ten industrial members: Cemex, Holcim (US) Inc., the International Center for Aggregate Research (ICAR), the National Ready- Mixed Concrete Association (NRMCA), the Portland Cement Association (PCA), S ika Technology, W. R. Grace & Co. - Conn., Verein Deutscher Zementwerke ev (VDZ), the Association Technique de l´Industrie des Liants Hydraulique, and Master Builders Technologies.
The consortium is governed by the VCCTL consortium oversight board, consisting of one representative from each of the ten companies and the VCCTL consortium manager from NIST. The oversight board meets two times per year to review research progress and set the scope and agenda of future research. Within each industrial participant's laboratory, one researcher is assigned to participate in the research programs of the consortium. Once per year, the most recent version of the VCCTL system software is installed on a Linux-based PC at each participating member's laboratory. As of 2003, the latest version of the VCCTL is 3.0. Note that version 1.1 of the public VCCTL system is available online at http://ciks.cbt.nist.gov/vcctl.
