:Portland CementConcrete and CementCement Production3.7 Hydrated lime (portlandite) Portland cement hydration results in the formation of a large amount of portlandite: 20–30% of the hydrated mass of cement according to the respective amounts of C3 S and C 2 S in the clinker. In concretes having a high w/c, this portlandite appears in the form of large hexagonal crystals, as shown in Figure 3.12.
