Question

Limestone and shale crushed and mixed. 2. In the kiln at 1480C, mix fuses and forms clinker which is ground and stored. 3. Clinker mixed with gypsum which slows setting time. 4. Clinker/gypsum ground and mixed to very fine cement powder and stored in a moisture-free environment.

a) Cement production
b) Glass production
c) Plastic production
d) Rubber production

Answer 1

Limestone and shale are crushed and mixed to produce clinker, which is ground and mixed with gypsum to form cement powder in a moisture-free environment.

Step-by-step explanation:

Limestone and shale are crushed and mixed to produce clinker, which is then ground and stored.

The clinker is mixed with gypsum to slow the setting time.

It is then ground and mixed to form a very fine cement powder and stored in a moisture-free environment.

This process is known as cement production.
