Over view:

Over view *Lime stone +shale/clay + heat=clinker+ exit gas *Clinker + gypsum= port land cement

Clinker chemistry:

Clinker chemistry  cement clinker contains four main minerals : Tri calcium silicate (typically about 65% of the total ) Di calcium silicate (typically about 15% of the total ) Tri calcium aluminate (typically about 7% of the total ) Tetra calcium alumino ferrite (typically about 8% of the total)

The final product of this phase is called “clinker”. These solid grains are then stored in huge silos. End of phase one.:
