2. Calcium hydroxide - Wikipedia

   en.wikipedia.org/wiki/Calcium_hydroxide

   Calcium hydroxide (traditionally called slaked lime) is an inorganic compound with the chemical formula Ca() 2.It is a colorless crystal or white powder and is produced when quicklime (calcium oxide) is mixed with water.

3. Lime (material) - Wikipedia

   en.wikipedia.org/wiki/Lime_(material)

   An example is when slaked lime (calcium hydroxide) is mixed into a thick slurry with sand and water to form mortar for building purposes. When the masonry has been laid, the slaked lime in the mortar slowly begins to react with carbon dioxide to form calcium carbonate (limestone) according to the reaction: Ca(OH) 2 + CO 2 → CaCO 3 + H 2 O.

4. Lime softening - Wikipedia

   en.wikipedia.org/wiki/Lime_softening

   Lime softening (also known as lime buttering, lime-soda treatment, or Clark's process) [1] is a type of water treatment used for water softening, which uses the addition of limewater (calcium hydroxide) to remove hardness (deposits of calcium and magnesium salts) by precipitation.

5. Calcium oxide - Wikipedia

   en.wikipedia.org/wiki/Calcium_oxide

   Calcium oxide (formula: Ca O), commonly known as quicklime or burnt lime, is a widely used chemical compound. It is a white, caustic , alkaline , crystalline solid at room temperature . The broadly used term lime connotes calcium-containing inorganic compounds , in which carbonates , oxides , and hydroxides of calcium, silicon , magnesium ...

6. Agricultural lime - Wikipedia

   en.wikipedia.org/wiki/Agricultural_lime

   Unlike the types of lime called quicklime (calcium oxide) and slaked lime (calcium hydroxide), powdered limestone does not require lime burning in a lime kiln; it only requires milling. All of these types of lime are sometimes used as soil conditioners , with a common theme of providing a base to correct acidity , but lime for farm fields today ...

7. Lime sulfur - Wikipedia

   en.wikipedia.org/wiki/Lime_sulfur

   About 2.2:1 is the ratio (by weight) for compounding sulfur and quicklime; this makes the highest proportion of calcium pentasulfide. If calcium hydroxide (builders or hydrated lime) is used, an increase by 1/3 or more (to 115 g/L or more) might be used with the 192 g/L of sulfur. If the quicklime is 85%, 90%, or 95% pure, use 101 g/L, 96 g/L ...
