This study has examined the effects of limestone characteristics (microstructure and texture) and calcination temperature on the reactivity of the produced quicklime. Two types of limestone have been calcined at four selected temperatures (900°C, 1000°C, 1100°C, 1200°C), and the produced quicklime was slaked.material is based on the classification of limestone quality based on the CaO content of Indonesian Cement Industry by [10][11] and [12] as shown in Table 1 and Table 2 CONSER-2022LQYHVWLJDWLRQRI3RUWODQG Hydration Properties

The quality of raw materials, especially limestone, which was used in plant 1, was a good-quality limestone, both in terms of chemical content and easily grinded rock texture. This affected the reduction in SO 2 concentrations carried in the kiln flue gas flow, caused by CaO levels generated in the calcination process in the cyclone preheater.Water quality index in Indonesia 2014-2021.
