Band 7+: The diagrams below show the stages and equipment used in the cement-making process, and how cement is used to produce concrete for building purposes.

The diagrams illustrate the process of cement production and its utilization in the creation of concrete for construction purposes.

Overall, the cement production involves five stages – crushing and milling of limestone and clay, mixing and heating the materials, grinding, and packaging. In contrast, concrete production entails combining 15% cement, 10% water, 25% sand, and 50% gravel in a concrete mixer to form concrete.

In the cement production process, limestone and clay are initially crushed and then turned into powder. The powdered materials are then mixed in a specific ratio and transferred to a rotating heater to undergo a heating process. Following this, the materials are subjected to grinding, resulting in the final product – cement. Finally, the cement is packed into bags for distribution.

In concrete production, the cement is combined with water, sand, and gravel in designated proportions. Specifically, the mix contains 15% cement, 10% water, 25% sand, and 50% gravel, with a clarification that the gravel signifies small stones. This concrete mixture is then ready for use in the construction industry.
