Quicklime CL 90
Ground quicklime CL 90-Q - low reactivity

Quicklime CL 90-Q ground is produced by calcining very pure limestone (CaCO3 content > 97.5%) and then ground to the required parameters.

Area Of Use

Due to its high chemical purity, high CaO content, reactivity of 5-11 minutes and yield, it is suitable for use in metallurgy, production of building materials (aerated concrete), environmental protection - especially treatment of flue gases and polluted water, road construction, glass industry, paper industry, production and processing of non-ferrous metals (manganese, lithium, aluminium), agriculture and chemical industry.
