Lime (material) Wikipedia

Natural hydraulic lime (NHL) is made from a limestone which naturally contains some clay. Artificial hydraulic lime is made by adding forms of silica or alumina such as clay to the limestone during firing, or by adding a pozzolana to pure lime. Hydraulic limes are classified by their strength: feebly, moderately and eminently hydraulic lime. Feebly hydraulic lime contains 5-10% clay, slakes in minutes, and sets

The basis of slag is limestone used as auxiliary material

During the process of reducing iron ore, it is necessary to remove the silica, alumina (Al 2 O 3), and other non-ferrous components contained in iron ore. The added limestone fuses with these components and lowers their melting point, making it easier to separate them from the iron and recover them. This recovered substance is slag.

Calcination Wikipedia

In limestone calcination, a decomposition process that occurs at 900 to 1050ºC, the chemical reaction is CaCO 3 (s) → CaO(s) + CO 2 (g). Today, this reaction largely occurs in a cement kiln.. The standard Gibbs free energy of reaction is approximated as ΔG° r ≈ 177,100 − 158 T (J/mol). The standard free energy of reaction is 0 in this case when the temperature, T, is equal to 1121 K
