The provided diagrams delineate the industrial processes involved in manufacturing cement and subsequently illustrate how this cement is utilised, alongside other constituents, to produce concrete. Overall, both processes are sequential, starting with raw materials that undergo various physical transformations and mixing stages to yield the final products. Cement production is a multi-stage industrial procedure involving heat, while concrete creation is a simpler mixing task, combining four specific ingredients in defined proportions. The initial stage of cement production involves crushing limestone and clay, which are then combined in a mixer. The resulting powder is fed into a rotating heater, where it is subjected to intense heat. Following this heating phase, the material moves to a grinder for further processing. The final output is cement, which is either stored in bulk or packaged into bags. To produce concrete, four main components are mixed together in specific quantities within a concrete mixer. Gravel, defined as small stones, constitutes the largest proportion at 50%. This is combined with 25% sand, 15% cement, and 10% water. Once these ingredients are thoroughly mixed, the concrete is ready for building purposes.
