2015-9-1 Limestone is converted into lime through heating in a kiln, a process known as calcination. When limestone is subjected to high temperatures, it undergoes a chemical decomposition resulting in the formation of lime (CaO) and the emission of carbon dioxide gas (CO 2). High-Calcium Lime CaCO 3 + heat CO 2 + CaO Dolomitic Lime CaCO 3 MgCO 3 + heat 2CO 2 + CaO MgO

2015-9-10 11.17.1 Process Description 1-5 Lime is the high-temperature product of the calcination of limestone. Although limestone deposits are found in every state, only a small portion is pure enough for industrial lime manufacturing. To be classified as limestone, the rock must contain at least 50 percent calcium carbonate. When the rock contains

2011-10-28 Because limestone is a naturally occurring mineral its chemical composition and physical characteristics vary not only from area to area but within veins of limestone in the same area. This variation in raw material results in variation of quality of the end product, which is calcium hydroxide.

The limestone cements, generally have lower paste water demand than the relative pure cements and the water demand decrease is mainly affected by the clinker type and limestone quality. In any case the properties of the limestone cements are affected by the interaction of the two components rather than their individual properties.

2015-9-1 Limestone can be categorized as either high calcium or dolomitic. Pure high-calcium limestone is 100 percent calcium carbonate (100 percent calcite or aragonite). Generally, limestone of this purity does not occur naturally. High-quality, high-calcium limestone would actually contain 97 to 99 percent calcium carbonate and 1 to 3 percent impurities.
