Solvay Process History. In 1861, after realizing the polluting impacts of the Leblanc Process, Belgian industrial chemist Ernest Solvay rediscovered and perfected Augustin Fresnel's reaction. This process recovered the ammonia in the reaction for reuse, therefore making it less detrimental to the environment.
the desired chemistry. The process of cement making is, however, remarkably flexible in terms of the raw materials that can be used to achieve required chemical compositions. Many limestone deposits, provided they are low in MgO, easily meet the requirements and a number of other CaOcontaining raw materials are known to be used. Alternative
