From where do we get cement for making our houses?a)We get it from the...
Cement is an essential material used in the construction of houses and buildings. It is a binding agent that is used to hold the bricks, stones, and other materials together to form a strong and durable structure. Cement is not found in its pure form in nature, so it needs to be processed at factories using materials obtained from nature.
Processing Cement
Cement is primarily made from limestone, a sedimentary rock that is abundant in nature. The process of making cement involves several steps:
1. Mining: Limestone is extracted from quarries or mines. Large rocks are blasted or excavated from the earth's crust using explosives or heavy machinery.
2. Crushing and Grinding: The extracted limestone is then crushed into smaller pieces using crushers or hammer mills. The crushed limestone is then ground into a fine powder in a grinding mill.
3. Mixing and Heating: The powdered limestone is mixed with other materials such as clay or shale in a rotating kiln. This mixture is heated to a very high temperature, typically around 1450 degrees Celsius. The intense heat causes chemical reactions to occur, resulting in the formation of clinker.
4. Grinding and Packaging: The clinker is cooled and ground into a fine powder, which is known as cement. This cement powder is then packed into bags or shipped in bulk to be used in construction projects.
Availability of Cement
Cement is produced in large quantities at cement factories located in various parts of the world. These factories are strategically located near limestone deposits to minimize transportation costs. Some countries have abundant limestone reserves, making them major producers of cement.
Conclusion
In conclusion, cement is not found in its pure form in nature. It is processed at factories using materials obtained from nature, primarily limestone. The process involves mining, crushing, grinding, mixing, heating, and grinding again to produce the final cement powder. Cement is widely available from cement factories around the world and is an essential component in the construction of houses and buildings.
