The Life-365 Consortium

History of Life-365 Service Life Predication Model™ Development

  • In 1998, during a National Institute of Standards and Technology (NIST) workshop the need for a consensus corrosion service life model was outlined.
  • In 1999, a consortium was formed within American Concrete Institute’s (ACI) Strategic Development Council (SDC) to fund development of the "Life-365" software program as the first step towards creating a consensus model.
  • In October 2000 Life-365 v1.0 is introduced to the concrete industry.
  • December 2001 the first revision of Life-365 v1.1 is released.
  • A second consortium was formed in 2005, which would continue the development and improvement of Life-365. The members of that consortium were:

    • Concrete Corrosion Inhibitors Association (CCIA)
    • National Ready-mixed Concrete Association (NRMCA)
    • Silica Fume Association (SFA)
    • Slag Cement Association (SCA)
  • At the Transportation Research Board’s (TRB) Annual Meeting in Washington, DC (January, 2008) Life-365 v2.0 with a completely redesigned user interface is released to industry.
  • May 2010 Life-365 v2.0.1 is released.
  • In January 2012, Life-365 v2.1.1 is released after an exhaustive 12-month process of verification and validation (including a review by the original developer).
  • Consortium III was formed in February 2012 to continue the development and improvement of Life-365. The members of that consortium are:

    • Cortec
    • Epoxy Interest Group - Concrete Reinforcing Steel Institute (CRSI)
    • Euclid Chemical
    • GCP Applied Technologies
    • Master Builders Solutions
    • National Ready-mixed Concrete Association (NRMCA)
    • Sika Corporation
    • Silica Fume Association (SFA)
    • Slag Cement Association (SCA)
  • In July 2013 Life-365 v2.2 of Life-365 was released.  This version allows the user to input local concrete-chloride profiles to customize the model to their worldwide locations and environments.   What had been the weak link in the model (the lack of chloride exposure information) may now become its most useful feature, especially to International users.
