EC number: 285-561-1 | CAS number: 85117-09-5 Mixtures of chemical substances produced by burning (below 1200°C) natural variants of limestone or chalk containing from 10 to 20%, or more, of clayey or siliceous materials which are predominantly SiO2, Al2O3 and iron oxide. Consist primarily of 2CaOsb.2, Ca(OH)2, CaO and 2CaOsb.2O3. 3CaO.2SiO2, 4CaOsb.2O3. Fe2O3, 2CaOsb.2O3sb.2, CaCO3 and SiO2 may also be included.
