The first diagram illustrates the process of manufacturing cement and the second diagram shows steps of producing concrete by using cement and other components.
Overall, it is clear that there are five stages in the production of cement, beginning with the input of limestone and clay and ending with packaging the products in bags.
To produce concrete, four different materials are mixed together.
At the first stage in the production of cement, limestone and clay are crushed to create a powder.
This powder is then mixed before it passes into a rotating heater to be heated at high temperature.
At the fourth stage of the process, the resulting material is ground (is put into a grinder machine) to create finished cement.
Finally, the cement is packaged in large bags and ready for the production of concrete.
To produce concrete, four different materials are prepared first, namely cement, water, sand and gravel with the percentages making up 15%, 10%, 25% and 50% respectively.
Next, all four materials are blended together in a concrete mixer to create finished concrete and then it can be used for building purposes.
