Limestone – Density – Heat Capacity – Thermal Conductivity

About Limestone. Limestone is very common in architecture, especially in Europe and North America. Limestone is extracted from quarries or mines. Part of the extracted stone, selected according to its chemical composition and optical granulometry, is calcinated at about 1,000 °C (1,830 °F) in different types of lime kilns to produce quicklime.
