The given diagram gives information about the cement producing process and in which way produced cement is used to prepare the concrete for constructing purposes!

In general, It can be seen that, how cement produced from limestone and other ingradients and concrete production stages from cement and other ingradients respectively. If we look at the first illustration, we can see the cement production process in details. In the beginning, limestone and clay grind up by crusher, as a result a mass becomes to the powder and it goes to the mixer. After that the mixed mass spend to the next stage such as rotating heater. In these stage the mixture heated by fire during the rotation. Finally, had been prepared mass reduced by Grinder and the cement powder would be ready to packaging. The second diagram gives data about concrete production. In order to produce concrete there are used several ingredients which are cement, water, sand and cravel in different amount. According to the details of illustration, the cement 15% and water 10 % added into the special container, after that sand 25 % and Gravel 50 % added respectively. Lastly, the gathered mass mixed by concrete mixer.
