decomposition of limestone
Nonisothermal decomposition of Indian limestone of marine ...
decomposition and the activation energy for decomposition of limestone is reduced and that the rate of decomposition is enhanced relative to pure calcium carbonate. The formation of portlandite and wollastonite are strongly exothermic and thus helps in maintaining the required retorting temperature. Keywords Limestone Thermal decomposition

What is the composition of a limestone? Quora
Limestone mainly includes CaCO3 that can directly be processed into stone material or burned into calcium lime. Limestone can be calcium or slacked lime. With CaO as the main ingredient and lump as the common shape, the pure calcium lime is black while the impure is light gray or pale yellow.
