The illustrated processes indicate the phases and materials which are used in order to make cement. After that it shows how concrete is produced by cement, which was made before, for building. In overview, the cement process consists of five main stages and two materials, and the concrete process involves four different substances which are mixed by a mixer.
Firstly, limestone and clay were crushed by crusher to convert to some powder. Afterward, they are mixed and transferred to a rotating heater. The resulted substance is heated and then the grinder is used in order to make the cement. Finally, the produced cement is gathered and kept in some bags.
Secondly, it is desired to produce concrete. The produced cement, water, sand, and gravel are needed to make concrete. The quantities of each material should be considered before mixing them up. In the concrete mixer should add 10 percent of water, 15 percent of cement, 25 percent of sand, and half of it belongs to small stones (gravel). If these materials mix correctly, concrete will be produced.
