Portland cement forms an alkaline slurry when mixed with water, initially due to dissolution of soluble alkali metal compounds from the cement clinker. This high pH is maintained via the hydration of cement clinker phases alite (Ca 3 SiO 5 ) and belite (Ca 2 SiO 4 ), which constitute 50–70% and 15–30% of the cement powder, respectively.

Cement clinker is a solid material produced in the manufacture of Portland cement as an intermediary product. Clinker occurs as lumps or nodules, usually 3 millimetres (0.12 in) to 25 millimetres (0.98 in) in diameter. It is produced by sintering (fusing together without melting to the point of liquefaction) limestone and aluminosilicate materials such as clay during the cement kiln stage.
