This cement is produced by burning a homogenized mixture of clay and limestone, resulting in intermediate product called clinker.

This inturn is mixed with gypsum in a specified proportion, and ground into fine powder to form the final product called Portland cement. This product is very useful in construction and engineering works of housing, buildings, bridges and cement concrete roads.

Grinding of clinker is the last and most energy-consuming stage of the cement manufacturing process, drawing on average 40% of the total energy required to produce one ton of cement. During this stage, the clinker particles are substantially reduced in size to generate a certain level of fineness as it has a direct influence on such performance characteristics of the final product as rate of hydration, water demand, strength development, and other.
