The physico chemistry in depth from the quarry to the final hydration
Our aim = sell cement
How?
By meeting our
customers’ requirements
Ease of use:
– workability
– lump free powder
– other customer’s requirement
Setting time
Resistance
Long term strength
Lasting quality, shrinkage
Swelling, expansion
Colour
All these characteristics are directly linked to the cement composition
Hence, the importance of knowing the physico chemistry in depth from the quarry to the final hydration
Prerequisites Composition of raw mix Composition of clinker
At first the raw material coming from the quarry has to be ground
You can add constituents to obtain the composition you require

Composition of raw mix

1st stage: evaporation

2nd stage: dehydration

3rd stage: decarbonation

Loss of ignition




4th stage: clinkerisation

5th stage: cooling

From raw mix to clinker…

Clinker minerals
