Quicklime
In a controlled environment, it is important to slake calcium oxide (quicklime) because it can produce relatively large amounts of heat. For water pH management, lime slurry mixes, lime slurry addition, soil regeneration and more, calcium hydroxide or hydrated lime is employed in an already neutralised state.
