Manufacturing Process of Portland Cement

Aug 26, 2014The manufacture of Portland Cement takes place in a number of steps: At TCL's Mayo Quarry, limestone, one of the main ingredients in cement manufacture, is excavated. The limestone raw material then goes through several categories of 'crushing', until it is fine enough for water, sand and iron oxide to be added to produce a mixture known as Slurry.

How Portland Cement is Made? Manufacturing Process of

Portland cement can be made by following two different processes – a dry one and a wet one. Joseph Aspdin first made portland cement in his kitchen stove in England in the 19th century. Lime and silica make up approximately 85% of portland cement. The materials that are commonly used are limestone, shells, chalk, shale, clay, slate, silica sand, and iron ore.
