the two diagrams beneath provide information about the stage and tool used in the process of cement-making and how cement is used to produce concrete for aim of building. It can be seen that the cement-making method involves variety of stage, beginning from crushing of limestone and clay and ending with contain in bag.
In the first process, limestone and clay is crushed together and become powder. Then powder is mix together after that it flow down to rotate by heater. Finally, powder is grinded which grinding powder it call cement. Cement will pack in bags for using in production of concrete.
The process of produce concrete is only simple that it start from mixing of cement, sand, water and gravel together by concrete mixer. The ratio of concrete is gravel which is small stones in an half, sand in one-fourths, cement in 15 percent and water in 10 percent. After that concrete finish and already for use in building.
