3. Hardened concrete
3.1 Cement hydration
The various cement constituents react with the mixing water (figure 7 ). Thus, calcium silicates (SiO 2 .3CaO and SiO 2 .2CaO) give a hydrated calcium silicate (2SiO 2 .3CaO.3H 2 O), known as C-S-H, which is primarily responsible for cement hardening. These reactions are accompanied by the formation of calcium hydroxide [Ca(OH) 2 ], known as "portlandite", which can react with other constituents, such as tricalcium aluminate (3CaO.Al 2...
