Stage of Cement Manufacture. There are six main stages of cement manufacturing process. Stage 1 Raw Material Extraction/Quarry. The raw cement ingredients needed for cement production are limestone (calcium), sand and clay (silicon, aluminum, iron), shale, fly ash, mill scale and bauxite. The ore rocks are quarried and crushed to smaller pieces of about 6 inches.

 ·  · There are more than twenty types of cement used to make various specialty concrete, however the most common is Portland cement. Cement manufacturing is a complex process that begins with mining and then grinding raw materials that include limestone and clay, to a fine powder, called raw meal, which is then heated to a sintering temperature as high as 1450 °C in a cement kiln.

PPC cement has to be cured for a lot longer, as well as the curing temperature does have a major impact on the development of its the temperature is low, the hardening process is sluggish. Although steam curing or humid heat treatment is being used, the hardening is intensified so that the cement isn't really ideal for winter building.

The manufacture of rapid cement hardening is a dry cement manufacturing process. Limestone and shale are used as a raw material in this cement and heated to form clinkers at extremely high temperatures. The lime and shale clinker are then mixed with a small amount of gypsum and ground to form rapidly hardening cement very finely.

Portland cement gets its strength from chemical reactions between the cement and water. The process is known as hydration. This is a complex process that is best understood by first understanding the chemical composition of cement. Manufacture of cement Portland cement is manufactured by crushing, milling and proportioning the following materials:
