The alkali activation of the calcined clays was analyzed based on the type and content of clay minerals, presence of calcite, calcination temperature, type of alkali activator, and curing conditions.

Calcite mineral Britannica

Between 60 and 70 elements have been recorded in minor or trace amounts in limestone analyses. Some of these elements may occur as substitutions within calcite; others seem more likely to represent minor constituents, such as clay minerals, within the analyzed rocks.. The chemical composition of calcite is responsible for the test that is widely used to identify it, especially in the field.

Kaolinite: The clay mineral kaolinite information and pictures

Kaolinite is a clay mineral, with a soft consistency and earthy texture. It is easily broken and can be molded or shaped, especially when wet. Kaolinite is a lackluster and uninteresting mineral on its own, but it occasionally forms interesting pseudomorphs, especially after feldspars. It is also a common accessory to other minerals, including gem crystals in decomposing feldspar pegmatites.
