Early clinker composition The phase diagram for the CaO SiO 2 C S system shown right was first accurately determined by Day Shepherd and Wright in shows that there are four stoichiometrically distinct calcium silicates each with multiple polymorphs CS C 3 S 2 C 2 S and C 3 cements contain mixtures of C 2 S and C 3 zone
In cement clinker production SSA can be effectively integrated into the raw feed at low contents up to about 5% though higher levels become problematic because of the suppression of the setting properties and early strength development The chemical composition of SSA and pozzolanic activity tests indicated that the material is somewhat reactive
