The pictures depict two manufacturing, cement and concrete. Overall, the two productions have different procedures since the cement manufacturing has its own stages, whereas the concrete needs only the rate of ingredients to mix it. The one production to be described is the cement. In the first phase, limestone and clay go through the crusher before mixing together. The mixed material is conveyed into the spinning vat with fire heating, continues, dumped on the grinder to be crushed which is subsequently produced as cement and it is packed into the bags as the final stage. The other one is the concrete. As mentioned above, concrete does not go through certain sequences but the percentages of the respective material. The largest rate is small stones, so-called ‘Gravel’, being 50% of the total, it is followed by that of sand, a quarter of proportion. The concrete consists of 10 percentages of water mixing the ingredients well, in addition, the ratio of cement only 5% higher than that of water. Afterward, all the ingredients blend in the rotatable concrete mixer.
