The visual diagrams illustrate the process of cement and concrete production.
Overall, cement and concrete production come from different origins. While cement is predominantly a product of limestone and clay, concrete is mainly composed of small stones and sand. Interestingly, cement production starts by crushing limestone and clay to produce a powder. This powder is then transported to the mixer, which is connected to a rotating heater. Lastly, after the powder is heated to a specific temperature, it is placed on a grinder, and the finished result is cement.
On the contrary, concrete benefits from cement to uphold its production. Indeed, cement (representing 15%) is mixed alongside water, sand, and finally gravel. The most dominant minerals used during the process are small stones, better known as gravel, occupying half the materials used for the production. Compared to cement, concrete production is extremely simple, requiring all these materials to be mixed in a mixer.
