Shreya Here

Cement is a man-made material. It is a binding agent that is used to make concrete, mortar, and other building materials. Cement is made by heating limestone, clay, and other materials at very high temperatures, which causes them to chemically react and form a hard, stone-like substance. The process of making cement is energy-intensive and involves the use of large kilns, so it is not considered a natural material. However, the raw materials used to make cement, such as limestone and clay, are naturally occurring materials.

Hi mam I am Chanchal....
Cement isn't salt of naturally occurring organic material. It is produced from a mixture of limestone nd clay that's charred and then ground up.... So I think cement is man made...😃
By the way it was a great session mam thankyou

Answer of home question - MAN MADE🎉🎉🎉
I HOPE YOU REACH 100K SOON 🎉🎉🎉❤

[@wxyzabcdaaaabbbb]

Cement is a man made resource but it is derived from natural things like limestone, clay, etc. Since it is used in making buildings, it's a man made resource. Whenever we use the natural things to make buildings, machinery, etc., they become man made or human made resource.
Loved the session🥳 Thank you ma'am for this wonderful session 🙏

[@kavitasatyamjakhar6902]

Cement is artificial but it is made from natural resources/materials.
Thank you mam 😊😊

[@riddhichatterjee3205]

Cement is both man made and natural because it is a grind of rocks and when it's mixed with chemical so it's natural and man-made respectively

[@amazingfactbyaaradhya2523]

mam cement is artificial as well as natural because the cement we used today is man made and sometimes natural but in ancient times we use sticky rice as a cement also and the more fun fact is that the great wall of china is also made up of sticky rice
