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).

The main areas of usage and product characteristics

Used in the manufacture of light bricks and aluminum, this product has many features such as Improving the properties of white bricks by reducing the cracks, Increased fire resistance properties for bricks, Gradually drying the bricks during manufacture, Increased brick whiteness, The calcium oxide concentration is 92% , This product is distinguished by its high quality and high concentration
