2018-8-16 The key difference between quicklime and hydrated lime is that the quicklime (or burnt lime) contains calcium oxide whereas the hydrated lime (slaked lime) contains calcium hydroxide. The major source for both quicklime and hydrated lime is the limestone. Therefore, like limestone, these compounds are also alkaline.

2021-7-19 Quicklime also ships in larger consignments of approximately 26 tons, compared to 20 tons for hydrated lime and 8.5 tons of dry lime equivalent per shipment of CALSAFE. As a result, shipping costs per ton of quicklime are lower than the shipping costs per ton of hydrated lime or per ton of dry lime

Calcium Carbonate, quicklime and hydrated lime can all be used to adjust the pH of soils to give optimum growing conditions and hence improve crop yields. The use of quicklime, hydrated lime and/or blends of these with calcium carbonate and magnesium Limestone will help to speed pH adjustment which can help to treat conditions.

Read MoreHydrated lime and quicklime are both chemical compounds of calcium. Calcium is called calcium hydroxide when it is present in its hydrated form, and it is called calcium oxide (or quicklime) in its pure state. Calcium oxide is more reactive than hydrated lime and is also known to have a higher density.
