Cement clinker is a system of multiple artificial minerals produced through the burning of a raw mixture, similar to how granite is made up of some natural minerals. Individual components of clinker, unlike granite, cannot be distinguished with the naked eye because it is made up of fine-grained crystalline and amorphous phases.

Portland cement clinker's approximate mineral composition is as follows:

1. Tricalcium silicate (alite) - 3 CaO x SiO2 - 40-65%;

2. Dicalcium silicate (belite) - 2 CaO x SiO2 - 15-45%;

3. Tricalcium aluminate - 3 CaO x Al2O3 - 4-12%;

4. Tetracalcium alumoferrite - 4 CaO x Al2O3 x Fe2O3 - 12-25%.

The total content of alite and belite is usually between 70 and 80 percent. As a result, calcium silicates are quantitatively prevalent in Portland cement clinker. As a result, this cement was once known as silicate cement.

Clinker also includes small quantities of other calcium aluminates and aluminoferrites, as well as calcium ferrite, in addition to these basic minerals. Clinker also comprises an amorphous material in the form of uncrystallized glass, in addition to crystalline phases (6-10 percent ). Since magnesium carbonate is an almost unavoidable natural impurity in limestones, the clinker produces magnesium oxide in limited amounts (no more than 5%). As a result of incomplete clinker burning, i.e. defects in the firing technology, free calcium oxide (up to 1% ) can sometimes be contained in clinkerFinally, clinker can contain compounds formed by alkaline oxides of sodium and potassium (up to 1-2 percent). Raw materials and solid fuel ash are used to convert these oxides to clinker.

Knowing the properties of clinker minerals, especially the amount of heat released when interacting with water, as well as the mineralogical composition of this clinker, it is possible to identify the key features of the cement made from this clinker in a first approximation.
