The Chemical Composition of Marble Actforlibraries.org

The exact chemical composition of marble will greatly vary dependong on the location and the minerals or impurities present in the limestone during recrystallization. Typically, marble is composed of the following major constituents: 38-42% Lime (CaO), 20-25% Silica (SiO2), 2-4% Alumina (Al2O3), 1.5-2.5% various oxides (NaO and MgO), and 30-32% various carbonates (MgCO3 and others).

Marble Wikipedia

07/11/2001· Marble is a metamorphic rock composed of recrystallized carbonate minerals, most commonly calcite or dolomite. Marble is typically not foliated, although there are exceptions. In geology, the term marble refers to metamorphosed limestone, but its use in stonemasonry more broadly encompasses unmetamorphosed limestone.

02/12/2019· Marble is a metamorphic rock formed when limestone is subjected to high pressure or heat. In its pure form, marble is a white stone with a crystalline and sugary appearance, consisting of calcium carbonate (CaCO 3 ). Usually, marble contains other minerals, including quartz, graphite, pyrite, and

Properties of Marble Physical Thermal

The hardness of Marble is 3-4 whereas its compressive strength is 115.00 N/mm 2. Streak is the color of rock when it is crushed or powdered. The streak of Marble is white whereas its fracture is not available. Luster of Marble is the interaction of light with the surface of Marble. Luster of Marble is dull to pearly to subvitreous. Marble cleavage is perfect. The specific gravity of Marble is 2.86-2.87. Marble is opaque

Later physical deformation and chemical decomposition of the metamorphic marbles often produces attractive coloured and variegated varieties. Decomposition yields hematite, brown limonite, pale-green talc, and, in particular, the green or yellow serpentine derived from forsterite and diopside, which is characteristic of the ophicalcites or verd antiques. Earth movements may shatter the rocks

When it is formed from a limestone with very few impurities, it will be white in color. Marble that contains impurities such as clay minerals, iron oxides, or bituminous material can be bluish, gray, pink, yellow, or black in color. Marble of extremely high purity with a bright white color is very useful. It is often mined, crushed to a powder, and then processed to remove as many impurities as possible. The resulting

What are the characteristics of marble?

Higher temperatures often increase the rate of chemical changes; low temperatures can create the risk of “freeze-thaw” problems, and rapid changes of temperature can produce stresses in the material due to differential expansion. Most of the natural or inherent problems which can occur with marble require some degree of moisture to occur. However, other problems such as wind erosion and
