ACI: Chloride Diffusion Modelling in Pozzolanic Concrete in Marine Site

The American Concrete Institute (ACI) has released a paper called Chloride Diffusion Modelling in Pozzolanic Concrete in Marine Site.

The document was written by Atiye Farahani, Hosein Taghaddos, and Mohammad Shekarchi. The study developed an empirical model for predicting the chloride diffusion coefficient for silica fume, metakaolin, zeolite, and portland cement concretes under long-term exposure in the splash zone of Qeshm Island, Iran.

All investigations are based on 12 concrete mixture designs exposed to seawater for a maximum period of 50 months.

ACI says: “The empirical model is developed by applying regression analysis based on Fick’s Second Diffusion Law on the experimental results and those are compared with previous studies in this area.”

The comparisons suggest the predicted chloride diffusion coefficient level is within a +25% error margin in the specimens, ACI concludes.
