The chemistry and mineralogy of cement are complex. In simple terms, cement is a manmade mineral structure created at high temperatures, mainly comprising lime (CaO), Silica (SiO 2) and oxides of aluminum and iron (Al 2 O 3 and Fe 2 O 3). The cement making process can be divided; first "clinker" is made at temperatures of 1400 o C. …
