The diagram below shows the stages and equipment used in the cement-making-process, and the cement used to concrete for building purpose.

This diagram illustrates the procedure for making cement and also shows how it helps make concrete for construction. Overall, clay and limestone are used to make cement, and this method requires four stages. On the other hand, the four elements required for making concrete In the first picture, it is represented that the clay and limestone are equally put into the machine, and through the crusher, they are converted into powder. Afterward, they go through a mixture, where these substances can mix well; however, in the next phase, they are pushed into a rotating heater to heat them properly through rotation. Further, these foundations give more heat, so they can transform into cement. Furthermore, the next figure shows that for making concrete, four components are needed: 15% cement, 10% water, 25 percent sand, and 50 percent gravel. All these substances are put into the concrete mixer machine and rotated for some time, where they mix well. After the mixture is formed, it is used for building construction.
