Available Lime Index (as CaO) >85% Loss on Ignition 1.0-5.0% Residue on Slaking 600u m >5.0% Specific Gravity: 3.2 - 3.4 Bulk Density: 1000 - 1050kg/m3

CHEMICAL COMPOSITION

Generally Quicklime is the oxide of calcium – CaO Quicklime is usually made by calcining limestone. The heating process liberates carbon dioxide from the limestone leaving calcium oxide. Limestone = Calcium Oxide + + Heat Carbon Dioxide (CaCO3) = CaO + CO2 Constituents % Dry Calcium Oxide CaO >90.0% Magnesium Oxide MgO >2.0% Aluminium Oxide Al2O3 >1.0% Silicon Dioxide SiO2 >3.0%
