• The major use of quicklime is in the basic oxygen steelmaking (BOS) process. Its usage varies from about 30 to 50 kilograms (65–110 lb) per ton of steel. The quicklime neutralizes the acidic oxides, SiO2, Al2O3, and Fe2O3, to produce a basic molten slag. • Ground quicklime is used in the production of aerated concrete blocks, with densities of ca. 0.6–1.0 g/cm (9.8–16.4 g/cu in). NettetHydrated lime also called slaked lime is produced when water is added to calcium oxide (CaO, or quicklime). The result of this mixing of water and calcium oxide (quicklime) is an exothermic reaction known as slaking. The slaking reaction produces calcium hydroxide, (Ca (OH) 2 ). Initially, the calcium hydroxide is produced as a fine dry powder.
