Cement clinker - Wikipedia

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.

Black Concrete is Black... Or is it? | Concrete Decor

Jan 03, 2004· Where iron oxide pigments bond with portland cement and become a permanent part of the concrete matrix, carbon black does not. As water evaporates from the surface of concrete colored with carbon black, it can draw out the carbon, causing the concrete to fade. Sealing the concrete can prevent this, but the sealant must be reapplied periodically.
