The diagrams illustrate the processes of making cement and concrete. Overall, it can be seen that there are five stages in the cement production beginning with crushing limestone and clay and ending with packaging, meanwhile, the production of concrete has two stages. In the first process, limestone and clay are put through the crusher and converted into power. After that, the power is then poured into the mixer in which the modules are blended. In the next step, the product is heat through the rotating heater at a high temperature, followed by the grinding process to create cement which is ready for packing into bags and selling. In terms of concrete production. Cement, water, sand, and gravel are prepared with the percentage of 15%, 10%, 20%, and 50% respectively. After that, they are poured into a concrete mixer which became a form called concrete.
