  • Cement hydration - Understanding Cement

    If fine limestone is present, carbonate ions become available as some of the limestone reacts. The carbonate displaces sulfate or hydroxyl in AFm; the proportion of monosulfate or hydroxy-AFm therefore decreases as the proportion of monocarbonate increases.

  • Calcium carbonate - Essential Chemical Industry

    In the chemical industry, large quantities of limestone are heated to ca 1500 K to form calcium oxide, known as quicklime: Water can be added to lime to form calcium hydroxide. The process is known as 'slaking'. Solid calcium hydroxide is known as slaked lime or hydrated lime, and solutions and suspensions in water as milk of lime.

    The first gravimetric test was in 27 BC when Vitruvius measured limestone's change of mass as it calcined to lime. In modern chemical engineering, researchers apply the technique to derive conversions, kinetics, and mechanisms for any process with a change of mass by isothermal, non-isothermal, and quasi-isothermal methods.

  • Physical and Chemical Properties of Limestone - Big Chemical Encyclopedia

    Limestone and marble are chemically identical (CaC03) but differ in physical properties because limestone is composed of smaller particles of calcium carbonate and is thus more porous and more workable. Although both limestone and marble are used for buildings, marble can be polished to a higher sheen and is often preferred for decorative purposes.
