The Advantages of Portland-Limestone Cement Concrete

Aug 12, 2014 · When OPCs with up to 5% limestone are replaced with PLCs containing 10% to 15% limestone, the resulting impact per million tons of cement produced equates to 443,000 to 664,000 million BTU less clinkering energy used and 189,000 to 283,000 tons reduction of CO2 emissions. How does PLC affect the economics of a concrete mix design?

Limestone uses — Science Learning Hub

Calcium oxide, obtained from limestone, acts as a pH regulator when extracting gold from quartz. The chemical extraction of gold from powdered quartz rock uses a solution of sodium cyanide. In this cyanidation process, the pH of the solution needs to be maintained between 1011 to prevent the production of deadly hydrogen cyanide gas.

What happens when acid reacts with limestone? Questions

Jun 15, 2008 · Limestone is mostly made up of the mineral calcium carbonate (CaCO3). This is not very soluble, so rocks don't dissolve very quickly. But if you add an acid, you add hydrogen ions (H+), which will react with the carbonate to form hydrogen carbonate HCO3- ions, which are very soluble in water, and the limestone will dissolve. Or, if there is more acid, two hydrogen ions will
