A new publication titled “Rapid Prediction of Cementitious Initial Sorptivity via Surface Wettability” was published in npj Materials Degradation, in July 2023.
One of the tests to predict the durability of cement-based materials involves measurement of water uptake over time. This ‘sorptivity’ test, however, is laborious and time-consuming (continuous weight measurements over several hours to days).
Today, we report a rapid test method that exploits fundamental wetting characteristics of cementitious systems to predict their 6-hour initial sorptivity in a matter of few seconds. Enabled by computer vision, the quantification of drop spreading dynamics opens up a new pathway for rapid, automated, and affordable testing of cementitious systems.
This is the second article from our group’s Ph.D. candidate Hossein Kabir. Congratulations Hossein for this very interesting work!
