Lime is the most widely used reagent in water treatment applications. It is supplied in two forms: quick lime: CaO; slaked (or hydrated) lime: Ca(OH) 2. Warning: in both cases, these reagents will contain between 4 and 20% of solid impurities (CaCO 3, SiO 2 …). …
Lime softening, also known as Clark's process, is a type of water treatment used for water softening which uses the addition of limewater (calcium hydroxide) to remove hardness (calcium and magnesium) ions by precipitation.The process is also effective at removing a variety of microorganisms and dissolved organic matter by flocculation.
Lime has been used for many years to stabilize road beds and air fields, but now lime is also being used to stabilize buildings sites. Lime stabilization is used primarily to upgrade poor quality clay soils in order to provide adequate subgrade support- a prime requisite for good concrete slab performance.

Dip a scoop, which should have a capacity of about one cup, into the lime and pour the lime into the outhouse hole after each use. Sprinkle the lime slowly and gently to avoid producing dust clouds or getting the substance on your skin or in your eyes, which causes burns.
But the most common treatment is slaking, or addition of water to the quicklime. This is an exothermic reaction, which means it results in the evolution of a large quantity of heat to form calcium hydroxide or slaked lime. The process of hydration is carried out in a continuous hydrator, after which micron-sized slaked lime particles are produced.

The burnt limestone is crushed and slaked with water in rotating slackers to produce slaked lime or calcium hydroxide. The slaked lime is then added to the water as the main coagulant to destabilize the electrostatic charges of suspended particles in the water.
Modern cements are more sophisticated and "cure" more quickly than slaked lime, but lime continues to be a major compenent of modern cements. When quicklime is painted on wood, it forms a rock-hard white coating called whitewash. The Chemistry of Lye. Lye can be made very easily from lime and soda ash using a classic metathesis reaction:

In medicine, antacids containing small amounts of calcium carbonate are used in the treatment of 'acid stomach'. The chemical reaction occurring involves the neutralisation of excess acid with calcium carbonate. Brands such as Quick-Eze and TUMS have calcium carbonate as the 'active' ingredient.
The rock is light grey, and has medium grained or equigranular texture. It has massive structure, and the particle diameter is 2–3 mm. The rock contains dark minerals of hornblende and black mica, which accounts for 25%; and contains the light-colored minerals of plagioclase, potash feldspar, and quartz, which accounts for 75%.
