Solvay process Wikipedia

The Solvay process or ammonia-soda process is the major industrial process for the production of sodium carbonate (soda ash, Na 2 CO 3).The ammonia-soda process was developed into its modern form by the Belgian chemist Ernest Solvay during the 1860s. The ingredients for this are readily available and inexpensive: salt brine (from inland sources or from the sea) and limestone (from quarries).

The Advantages of Portland-Limestone Cement| Concrete

Aug 12, 2014· The limestone is more easily ground than the clinker, which is harder, and becomes concentrated in the finest particles. Overall fineness must be higher (for equivalent performance) for fineness of the clinker fraction to be similar to OPC. This means the production rate is slowed and some additional grinding energy is required.
