C3S is the most abundant mineral in portland cement, occupying 40–70 wt% of the cement, and it is also the most important. The hydration of C3S gives cement pastes most of its strength, particularly at early times. Pure C3S can form with three different crystal structures. At temperatures below 980˚C the equilibrium structure is triclinic.
