A glance at the diagrams provided reveal a stages of making a cement, and demonstrates the process of by using cement, how concrete is produced for construction purpose.
Overall, it is evident from the information provided that there are four main stages for cement making, whilst producing concrete requires a proper proportion of four raw materials.
From the information supplied, first stage of manufacturing cement begins with crushing limestone and clay together to form a powder mix of the two materials. Secondly, the powder will be placed in the mixer, and proceed to rotating heater(heated machine with constantly rotating motion). Finally, heated powder go through grinding stage to create cement. By packing the final product, cement is ready to be used for concrete.
As the second diagram illustrated, the portion of the concrete mix must include 15% cement, 25% sand, 50% gravol(small stones), and 10% water. WIth continuous mixing of spinning motion, the concrete is ready to be used for the manufactory.
