Astra Lime / Slow Reaction
ASTRA LIME / Slow reaction is calcium oxide (CaO) (quick-burning lime) produced through the process of burning limestone (CaCO3) in a chemical process called calcination, and this process is carried out in vertical kilns at a temperature of (1250-1300 ° C) , which leads to the decomposition of limestone (calcium carbonate) into (calcium oxide) and carbon dioxide Our product is of high quality, very fine powder with excellent flowability, reaction of calcium oxide with water is very slow (R 60 = 3 – 15 minutes).
