  Cement Hydration - an overview | ScienceDirect Topics

  Portland cement P.-C. Aïtcin, in Science and Technology of Concrete Admixtures, 2016 3.7 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 …
