Calcium carbonate - Wikipedia

Calcium carbonate is a chemical compound with the formula CaCO3. It is a common substance found in rocks as the minerals calcite and aragonite (most notably as limestone, which is a type of sedimentary rock consisting mainly of calcite) and is the main component of eggshells, snail shells, seashells and pearls. Calcium carbonate is the active ingredient in agricultural lime and is created when calcium ions in hard water react with carbonate ions to create limescale. It has medical use as a calcium supplement or as an a

Limestone - Wikipedia

Limestone is composed mostly of the minerals calcite and aragonite, which are different crystal forms of calcium carbonate (CaCO 3). Dolomite, CaMg(CO 3) 2, is an uncommon mineral in limestone, and siderite or other carbonate minerals are rare. However, the calcite in limestone often contains a few percent of magnesium. Calcite in limestone is divided into low-magnesium and high-magnesium calcite, with the dividing line placed at a composition of 4% magnesium. High-magnesium calcite retains the calcite min

Stabilisation of weathered limestone surfaces using ...

01-04-2021  Calcium carbonates and other constituents of limestone dissolve in acidic groundwater due to the rock's hydrophilic characteristics (Rodriguez-Navarro and Sebastian, 1996; Massey, 1999). This can result in embrittlement by internal or surficial mineral alteration and such weathering can strongly impact rock stability (Abbaszadeh et al., 2016).
