The cement production process requires thermal energy (heat) for production of clinker which is the primary ingredient for the manufacture of cement. Clinker production typically occurs in kilns heated to about 1450 C. Clinker production is the most energy-intensive process in cement manufacturing.

    Gypsum (CaSO4·2H2O) is the most common sulfate mineral on Earth and is also found on Mars. It is an evaporitic mineral that predominantly precipitates from brines. In addition to its precipitation in natural environments gypsum also forms an undesired scale in many industrial processes that utilize or produce brines. Thus better insights into gypsum formation can contribute to the
