METHOD OF TEST FOR THE DETERMINATION OF

Dolomitic limestone may be recognized by determining CaO : MgO ratio. Clay content may be determined by measuring alumina (Al 2O 3) content. 1.3 Carbonate rocks which are not alkali-carbonate reactive may be alkali-silica reactive. This test procedure does not determine the potential for alkali-silica reactivity. 2. RELEVANT DOCUMENTS

Limestone is used in the flue gas desulphurization process due to its ability to form sulfur compounds. Different qualities of limestone absorbents can be used in the process and it is therefore important to measure the reactivity of these materials. A limestone with a 90 to 95% of calcium carbonate is used to prepare limestone slurry for the flue gas desulphurization.
