The substance called clinker is dark gray as the color that appears after firing while cement is produced and it is called the material that resembles the image of marble. Its production occurs as a result of heating and combining the material called limestone and clay at approximately 1500 degrees in the furnace until it becomes liquid.
Their dimensions vary are between 3 and 25 mm according to the general average. While the use of clinkers can be carried out by fine grinding, the most useful and preferred reason is that they can be stored for a long time as long as they remain in a dry environment.
