Portland phases
WebThe Ca 2 + of the original cement is present in all hydrated phases as the basic component. The SiO 44 − originally present in C 3 S and C 2 S is mainly incorporated into the C-S-H phase. A small amount of silica is also incorporated in the portlandite phase which is formed in the hydration of C 3 S and C 2 S together with C-S-H. WebThe processing of Portland cement clinker is the most energy-intensive phase in the cement manufacturing process, accounting for approximately all of the energy and nearly all of the fuel used.
