Question

Among the following components of cement, which is present in the highest amount?
A.$C{a_2}Si{O_4}$
B.$C{a_3}Si{O_5}$
C.$A{l_2}{O_3}$
D.$C{a_3}A{l_2}{O_6}$

Answer 1

Hint:Cement is a universal binder. It is used to set sand, bricks and other materials together and bind them together by setting them and hardening them to bind them together. It is not a naturally occurring chemical but is made from main 8 ingredients processed together.

Complete answer:
Cement is a very important chemical compound which is used in our day to day life to bind together materials. It sets different materials together by forming a hardened layer between the materials. It is not a naturally occurring compound; instead it is made up of 8 main ingredients mixed together and processed to produce cement. The different ingredients used are extracted from various naturally occurring materials like clay, sand, limestone, chalk and iron ore.
When cement is added to bind materials then water is mixed with cement for making cement easier to apply and pour and also helps to harden the mixture better but water and cement don’t hold well together and thus, sand is added to cement for better binding between materials. The mixture of cement, water and sand is known as mortar and has better binding capacity. When gravel is added to this mixture of water, cement and sand then it becomes concrete.
We must know that concrete has better binding and holding capacity than cement. Concrete is very durable and lasts for a very long time as compared to the durability of cement.
There are many types of cement that are used and the most common is the Portland cement which is used. Among the 8 main ingredients that are processed together to make cement the component which is present in the highest amount is among the given options is $C{a_3}Si{O_5}$.

Thus, the correct answer of the above question is option (B) $C{a_3}Si{O_5}$.

Note:
There are various types of cement which differ on the basis of the composition of various ingredients present. The other main components include tricalcium silicate, tricalcium aluminate and dicalcium silicate.
