Modern cement is made by heating a crushed mixture of limestone and clay or slag to a very high temperature. The mixture is heated in a huge furnace until large, glassy cinders called clinkers are formed. The clinkers are then ground into a powder . When water is added to the powder, a complicated chemical reaction takes place.

sand, lime, silica, gypsum and other agregate substances. It can vary since there are different types of cement. When all of those are mixed with water, you get Concrete.
