Overview of the Concrete Hydration Process
In the first step, called dissolution, the cement dissolves, releasing ions into the mix water. The mix water is thus no longer pure H2O, but an aqueous solution containing a variety of ionic species, called the pore solution. The gypsum and the cement minerals C 3 S and C3A are all highly soluble, meaning that they dissolve quickly. Therefore ...
