Provided are two pictures that depict the typical techniques and machines used in the process of making cement and how concrete is manufactured for construction.
Overall, it is apparent that there are three main stages in producing cement, which are crushing, heating, and packaging; meanwhile in making concrete, there is solely one step.
Looking at the first photo that displays the process of manufacturing cement in more detail, some raw materials which are limestone and clay, are put into a crusher to be converted into powder. After that, it is delivered to a mixer, then moved forward to a rotating heater via a pipe. The last step is putting the mixture into a grinder to create cement for packaging.
Moving onto the second process, which is about concrete production, there are some other ingredients that are added to a concrete mixer machine: gravel accounts for a half, while sand accounts for just a quarter, with concrete and water are 15% and 10%, respectively.
