What is Cement and How it is Manufactured?

Cement is a binding substance used to bind other buildings or civil construction materials like bricks, stones, gravel, tiles, etc. Cement can be set and hardened independently and can bind other building materials together. It is a very fine powder containing limestone, clay, silica, and alumina. Also contains bauxite and iron oxide.
