  2. Lime plaster - Wikipedia

    en.wikipedia.org/wiki/Lime_plaster

    When the plaster is dry, the pH falls to about 8.6. Non-hydraulic lime plaster requires moisture to set and has to be prevented from drying for several days. The number of qualified tradesmen capable of plastering with lime has declined due to industrialization, deskilling of trade crafts, and widespread adoption of drywall and gypsum veneer ...

  3. Calcium oxide - Wikipedia

    en.wikipedia.org/wiki/Calcium_oxide

    Calcined gypsum is an alternative material in industrial plasters and mortars. Cement, cement kiln dust, fly ash, and lime kiln dust are potential substitutes for some construction uses of lime. Magnesium hydroxide is a substitute for lime in pH control, and magnesium oxide is a substitute for dolomitic lime as a flux in steelmaking. [28]

  4. Lime (material) - Wikipedia

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

    Pure lime is pure white and can be used for whitewash, plaster, and mortar. Pure lime is soluble in water containing carbonic acid, a natural, weak acid which is a solution of carbon dioxide in water and acid rain so it will slowly wash away, but this characteristic also produces autogenous or self-healing process where the dissolved lime can ...

  5. Hydraulic lime - Wikipedia

    en.wikipedia.org/wiki/Hydraulic_lime

    Eminently hydraulic lime (NHL 5) is used for external work in exposed areas, such as chimneys and for floor slabs/underpinning. Eminently hydraulic lime contains clay in the range of 21% to 30%. Properties of eminently hydraulic lime are close to those of cement. Eminently hydraulic lime sets within one day after the addition of water.

  6. Tricalcium phosphate - Wikipedia

    en.wikipedia.org/wiki/Tricalcium_phosphate

    It is also known as tribasic calcium phosphate and bone phosphate of lime (BPL). It is a white solid of low solubility. Most commercial samples of "tricalcium phosphate" are in fact hydroxyapatite. [4] [5] It exists as three crystalline polymorphs α, α′, and β. The α and α′ states are stable at high temperatures.

  7. Lime mortar - Wikipedia

    en.wikipedia.org/wiki/Lime_mortar

    Lime comes from Old English lim ('sticky substance, birdlime, mortar, cement, gluten'), and is related to Latin limus ('slime, mud, mire'), and linere ('to smear'). [7] Mortar is a mixture with cement and comes from Old French mortier ('builder's mortar, plaster; bowl for mixing') in the late 13th century and Latin mortarium ('mortar'). [7]

  8. Aqion - Wikipedia

    en.wikipedia.org/wiki/Aqion

    Aqion is a hydrochemistry software tool. It bridges the gap between scientific software (such like PhreeqC [1]) and the calculation/handling of "simple" water-related tasks in daily routine practice.

  9. Descaling agent - Wikipedia

    en.wikipedia.org/wiki/Descaling_agent

    Limescale build-up inside a pipe reduces both liquid flow and thermal conduction from the pipe, so will reduce thermal efficiency when used as a heat exchanger.. A descaling agent or chemical descaler is a liquid chemical substance used to remove limescale from metal surfaces in contact with hot water, such as in boilers, water heaters, and kettles.
