The given diagrams explain how cement is produced and how it’s used to make concrete, which is used for construction. They show the steps from getting raw materials to using concrete in construction.
Overall, cement production is a multi-stage process that requires several pieces of equipment, while concrete production is a simpler process of mixing ingredients.
The production of cement begins with the crushing of limestone and clay into a fine powder. This powder is then mixed and heated in a rotating heater. The heated material is then ground into cement powder by a grinder. Finally, the cement is packaged into bags.
The second diagram shows the process of making concrete, which uses cement as one of its ingredients. Concrete is made by mixing four materials in a concrete mixer. The largest proportion of the mixture is gravel, which makes up 50% of the total. Sand accounts for 25%, while cement makes up 15%. The remaining 10% of the mixture is water.
The four ingredients are combined in the mixer to produce concrete.
