5.3 The Hydration Reactions in Concrete

The state of water in cement paste and in CSH gel is discussed further in Section 5.6. The kinetics of hydration of C 3 S are substantially similar to those of Portland cement as a whole (see Figure 51). Much of the reaction occurs during the first few days, leading to substantial strength gains and reduction in capillary porosity.
