  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. Annually, approximately 125 million tons of calcium hydroxide are produced worldwide. [8]

  3. 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 ...

  4. 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.

  5. Lime mortar - Wikipedia

    en.wikipedia.org/wiki/Lime_mortar

    If the quicklime is slaked with an excess of water then putty or slurry is produced. If just the right quantity of water is used, the result is a dry material (any excess water escaping as steam during heating). This is ground to make hydrated lime powder. Hydrated, non-hydraulic lime powder can be mixed with water to form lime putty.

  6. Limepit - Wikipedia

    en.wikipedia.org/wiki/Limepit

    The limestone blocks were then crushed, afterwards slaked (the process of adding water and constantly turning the lime to create a chemical reaction, whereby the burnt lime, or what is known also as calcium oxide, [7] is changed into calcium hydroxide), and mixed with an aggregate to form an adhesive paste (plaster) used in construction and for ...

  7. Lime plaster - Wikipedia

    en.wikipedia.org/wiki/Lime_plaster

    The resulting substance, known as quicklime or lump-lime, was subsequently pulverized into a fine powder and combined with water in a process called "slaking." Through this procedure, a fundamental binding agent called " lime putty " was created and utilized for plastering purposes.

  8. 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 ...

  9. Lime kiln - Wikipedia

    en.wikipedia.org/wiki/Lime_kiln

    Rotary lime kiln (rust-colored horizontal tube at right) with preheater, Wyoming, 2010 Traditional lime kiln in Sri Lanka. A lime kiln is a kiln used for the calcination of limestone (calcium carbonate) to produce the form of lime called quicklime (calcium oxide). The chemical equation for this reaction is: CaCO 3 + heat → CaO + CO 2
