The provided diagrams illustrate the processes by which cement and concrete are produced, respectively.
From the overall perspective, it is prominent that the manufacturing of cement requires multiple stages, while that of concrete is relatively straightforward.
For cement to be produced, limestone and clay are first poured into a crusher, squashing the materials into powdered form. Next, the particles are evenly blended by machinery before flowing through pipes to a central heater. During this stage, the heater rotates gradually, ensuring a homogeneous admixture. The resultant product then undergoes a process of grinding, converting it to usable cement, which is then packaged into discrete bags.
On the other hand, the production of concrete simply involves the mixing of several ingredients in one go, in accordance with their respective proportions. Components, namely 15% cement, 10% water, 50% gravel, and 25% sand, are each poured into a vast mixer, forming concrete after a few rotations.
