Band 8: The diagram below shows the stages and equipment used in cement
Cement is then combined with three other materials to create concrete. While the process of making cement uses a number of tools, the production of concrete is simpler and requires only a concrete mixer. In the first stage of making cement, limestone and clay are crushed together to form a powder using a crusher.

Cement
Cement is produced by a high-temperature (about 1500 °C) reaction in a rotary kiln of carefully proportioned and blended ratios of lime (CaO), silica (SiO 2), alumina (Al 2 O 3), and iron oxide (Fe 2 O 3).The production of cement is a chemical process requiring an accurate blend of the previously cited four key organic oxides and the limitation of several undesirable oxides …
