Dolomite, a calcium magnesium carbonate (CaMg(CO 3) 2) can also be calcined to form dolomitic lime, which has different reactivity due to the presence of MgO. These processes are called calcination. Lime can be mixed with water to form hydrated lime (Ca(OH) 2), which some also call lime.

Calcined clay is one of the most economical SCM due to its excessive availability in nature [65]. However, its purest form i.e., metakaolin requires additional processing which makes it much more costly. An alternate is in the form of brick which is crushed, grinded, and then used as calcined clay [66]. This also seems impractical due …

Quicklime is calcium oxide. It is a white powdery substance that comes out of the lime kiln after calcination is complete. If the original limestone was a dolomitic rock that included magnesium carbonate along with the calcium carbonate, the dolomitic quicklime made from it will contain magnesium oxide along with the calcium oxide.
