01 / Technical dossier
The material. The evidence.
Reference properties and the analytical work needed to assess this material for industrial use.
TO-REF-LIMESTONE
Revision 1.0 · Technical reference
Material identity
Main carbonate commonly CaCO₃
A carbonate rock, not a chemically pure compound. Calcite, dolomite and non-carbonate impurities must be quantified.
