HEY!!
Composition. Portland cement consists essentially of compounds of lime (calcium oxide, CaO) mixed with silica (silicon dioxide, SiO2) and alumina (aluminum oxide, Al2O3). The lime is obtained from a calcareous (lime-containing) raw material, and the other oxides are derived from an argillaceous (clayey) material.

A cement is a binder, a substance used for construction that sets, hardens, and adheres to other materials to bind them together.
The main features of these cement ingredients along with their functions and usefulness or harmfulness are given below:
Lime: Lime is calcium oxide or calcium hydroxide. ...
Silica:Silicon dioxide is known as silica, chemical formula SiO2. ...
Alumina: Alumina is Aluminium oxide. ...
Magnesia: Magnesium Oxide.
Iron oxide: Chemical formula is Fe2O3.
Iron oxide imparts color to cement.
It acts as a flux.
The most common raw rock types used in cement production are: Limestone (supplies the bulk of the lime) Clay, marl or shale (supplies the bulk of the silica, alumina and ferric oxide)
