From the set of illustrations, the first picture offers details regarding the various stages and equipment used from the production of cement from the raw materials; whereas, the second diagram shows how concrete is made.
Describing the cement production in detail, the process commences with the measured amount of limestone and clay being crushed in a crusher that results in powder. This powdered mixer is then passed through a rotating heater. Following this, the hot mixture is grounded to fine cement. Eventually, it is packaged and ready to be transported for on-site use.
Focusing on the latter diagram, it can be inferred that concrete is made up of half gravel, quarter sand, 15% cement, and 10% water. All these are added together in a cylindrical drum and rotated until the concrete is yielded. The thoroughly mixed concrete is ready for immediate further use.
Overall, it can be seen that cement production is a 5 stage process from mixing the ingredients to bagging cement; whereas, concrete making is simpler that involves mixing 4 ingredients in a concrete mixer.
