Abstract: Cement hydration is a key process to determine properties such as rheological property, mechanical property, volume stability and durability of cementitious materials. The hydration process during induction period makes an important role on the property development of cementitious materials. Therefore, understanding the hydration mechanism of cement and clarifying the hydration process of main cement clinker monominerals such as tricalcium silicate (C3S) system and tricalcium aluminate-gypsum (C3A-CH2) system during induction period would find out how to control the property development of cementitious materials in a better way. On this account, thermodynamic mechanism of cement hydration was reviewed. The hydration process and hydration mechanism of C3S system and C3A-CH2 system during induction period were also discussed. However, limited to the current research methods, the interrelation and interaction of various monominerals systems in the induction period of cement are still not fully clarified, and further exploration is needed.

Key words: hydration mechanism, tricalcium silicate system, tricalcium aluminate-gypsum system, induction period, hydration thermodynamic
