Life-365 is software designed to estimate the service life and life-cycle costs of alternative concrete mixture designs proportions and and life-cycle costs of alternative concrete mixture designs proportions and corrosion protection systems.  It follows research-based methodology developed by the Life-365  Consortium I and II groups of companies, that gives estimates on the effects of design, chloride exposure, environmental temperature, high-performance concrete mixture proportions, surface barriers, and steel types on the service life and life-cycle cost of steel-reinforced concrete structures.

The simplistic model is a fundamental tool for design consultants of steel-reinforced concrete structures that will be exposed to chlorides, who wish to estimate the service life and life cycle costs of alternative protections systems in their design.

 

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.

  • August 2001 Life-365 v1 is released to industry.

  • A second consortium was formed in 2005, that would continue the development and improvement of Life-365.  The members of that consortium are the Cement Slag Association (CSA), the Concrete Corrosion Inhibitors Association (CCIA), the National Ready Mixed Concrete Association (NRMCA) and the Silica Fume Association (SFA).

  • At the Transportation Research Board’s (TRB) Annual Meeting in Washington, DC (January 2008) v2 of Life-365 is released to industry.
