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.
Mar 19, 2021· Back to the above plot, we recognise that the amount of residual (unreacted) Cement SR clinker remains constant (a gray area at the bottom) at the level set in the parent recipe (28 days). This is not a too realistic scenario because in the real world, cement carbonation (or ingress of any other ions) is a slow process controlled by diffusion.
