explain the process of making concrete building construction

Regarding the second diagram, cement is used for concrete production which accounts for 15% of total ingredients to be used. And finally, it is passed through grinder to make it fine particles which is then packed into bags ready to use.

The mixed powder is then passed to next station where it is heated by rotating heater to make cement granules. Overall, cement which is mixed with different ingredients(water, sand, and gravel) is produced from 4 main stages where raw materials (Limestone and Clay) are used.Īt first, limestone and clay is passed through crusher to break it down in the form of powder which is then passed through the mixer. The diagram illustrates the raw materials and the process with the corresponding equipment required for making cement and how the concrete is produced for building purposes using cement and other ingredients.

Each body paragraphs explained the steps of each process in a logical order. The body paragraphs are organised well and linking devices are used flexibly and accurately. The overview contains key features of both diagrams and also highlights the connection between them. These are all poured into a concrete mixer which continually rotates to combine the materials and ultimately produces concrete.Ĭomments: This diagram gives a concise introduction.

The other materials used are sand (25%), cement (15%) and water (10%). Regarding the second diagram, concrete consists of mainly gravel, which is small stones, and this makes up 50% of the ingredients. The final product is afterwards put into bags ready to be used. The resulting mixture is ground in order to produce cement. This powder is then combined in a mixer before passing into a rotating heater which has constant heat applied at one end of the tube. In the first stage of making cement, limestone and clay are crushed together to form a powder. While the process of making cement uses a number of tools, the production of concrete requires only a concrete mixer. Overall, limestone and clay pass through four stages before being bagged ready for use as cement which then accounts for 15% of the four materials used to produce concrete. The diagrams illustrate the way in which cement is made and how it is then used in the process of making concrete.
