Two diagrams illustrate general manufacturing processes to make up cement and concrete, which are some of the main materials for building construction.
Overall, there are five distinct stages in cement production, while to sufficiently generate concrete, it seems to have more three ingredients apart from cement.
In terms of cement-making term, initially, limestone and clay are crushed to easily move over a mixer then. After that, the mixture, through pipes, goes to the third step, which is heated by rotating heater. Subsequently, a grinder is used to create the last form of cement and this is packaged into bags then to be sent to site construction eventually.
In another sector, cement represents 15% into a mixture involved 10% of water, 25% of sand and a majority of gravel at a half. This compound, in the next phase, is rotated by a concrete mixer until reaching an efficient level of concrete, making up the structure of building.

It seems that the submission is duplicated.
Anyway, I attached the corrected version in case you need it.
