The pictures given depict the process of making concret that is essential in building construction and cement producing procedure including some equipments in that procedure.

In terms of cement making process, limestone and clay are used as basic ingredients. After they are crushed into powder and then mixed by crusher and mixer namely, they are being heated by passing through rotating heater below the mixer. Lastly, the heated mixture of powders are grinded  by grinder to cement before they are packaged into bags.

The cement which was produced as discripted above, took up 15% of concrete producing materials. The concrete making process can be seen as a great mixing process of four different materials including the cement we examined right before. In a huge rotating congrete mixer, four other materials are poured to produce concrete. The proportion of them is consisted of 50% of gravels that are small stones, 25% of sands, 15% of cement and 10% of water repectively.  

After successfully finishing these sequence, we can finally secure precious materials to construct buildings.

Until now, we was able to saw the concrete making process including cement produntion process that is holding 15% of concrete making materials with simple but explanatory and useful two pictures given.
