Main raw material of Portland cement

History of Portland Cement in the United States

 · On the other hand portland cement is an artificial mixture of raw materials has a calcination at a temperature above 2 000 degrees Fahrenheit and purer raw materials were used than necessary for natural cements. The raw materials used in the manufacturing of portland cement at this time were cement rock limestone shale and coal.

Raw materials used for Cement ProductionINFINITY FOR

Marls are an excellent raw material for cement manufacture because they contain the lime and the clay component in an already homogenized condition. Calcareous marl of the chemical composition equal to that of Portland cement raw mix are used for the manufacture of socalled natural cement however deposits of such raw materials are not common.
