Life-365 is a standard model developed for predicting the Service Life and Life-Cycle Cost of Reinforced Concrete exposed to chlorides. An industry consortium consisting of National Ready mixed Concrete Association, Concrete Corrosion Inhibitor Association, Slag Cement Association and the Silica Fume Association was formed to fund the development of Life 365 v2.0.

Currently, Version 2.0 of the standard model was released January 2008 and is available for downloading below. Please note that the download package contains an extensive manual that explains the basis of the model as well as includes instructions for its use.

The Consortium welcomes and needs Industry input for further development of the model. The goals of the development process will be in harmony with ACI Committee 365, "Service Life Prediction"
