The pictures illustrate the manufacturing process of cement and then, how it is used to produce concrete. Overall, there are various steps in both procedures, starting from mixing limestone and clay, and culminating in the concrete production with the help of a mixer.

In the first stage, limestone and clay are crushed together in a crusher in order to form a powder. Secondly, the powder is put inside a mixer and then, it ends up in a rotating heater. While the powder is rotating in a clockwise direction, heat is applied and the Product is grinded in the grinder until the cement is finally produced. In the subsequent stage, the final product is put into bags, so it can be used to produce concrete.

According to the second diagram, 15% of the produced cement is mixed with 10% of water, 25% of sand, and 50% of gravel, which are small stones. All the materials are poured into a concrete mixer, which rotates in a clockwise direction to produce concrete.
