Abstract:
Over the past 15 years, Life-365 has been widely used to estimate the service lives of concrete structures exposed to environmental chlorides. The current version of Life-365 (v2.2) includes a module that can provide an estimate of surface chloride concentration (Cs) using information obtained through ASTM C1556, “Standard Test Method for Determining the Apparent Chloride Diffusion Coefficient of Cementitious Mixtures by Bulk Diffusion.” This addition allows users to develop more accurate predictions of chloride exposure and thus service life.
