Mintek Resources High Calcium Hydrated Lime

Ca(OH)2, Calcium Hydrate, Hydralime, Hydrated Lime, Slaked Lime

Although hydrated lime has additional uses in industries such as agriculture and post-industrial processes, Mintek primarily uses it as an anti-strip agent in asphalt applications and to dry, modify and stabilize soils.. Hydrated lime, when used as an anti-strip for asphalt, stiffens the binders in asphalt therefore improving resistance to rutting and moisture damage.

Hydrated lime is most commonly delivered via pneumatic trailer but is also available in super sacks.

As with any chemical, high calcium hydrated lime should be handled with respect.; Personal protective equipment is necessary is to protect dust particles from entering the eyes, respiratory system and to keep the material off bare skin.; In particular, gasketed safety glasses or goggles should be worn in dusty and/or windy conditions.

Hydrated lime is derived from quicklime, so to understand where hydrated lime comes from you must first understand where quicklime comes from.; Quicklime is produced by subjecting limestone, or calcium carbonate (CaCO3), to high temperatures for a long period through a process known as calcining.; During calcination, CO2 is driven off leaving only the oxide portion, calcium oxide, or quicklime.; Quicklime can be further processed into hydrated lime by adding the right proportion of water and thoroughly agitating the mixture.; This hydration process produces a low-density, dry, bulk powder that is high in purity.
