How Lime is Made
To cook or “calcine” limestone, there must be a significant transfer of heat to the limestone In general, the heat transfer from the fuel source to limestone can be divided into two stages: Calcining – the kiln fuel is burned in the preheated air from the cooling zone and, as the limestone moves down the kiln, the heat turns the limestone into quicklime and carbon dioxide (CO 2 )Additionally, many factories in Erbil city in the Iraqi Kurdistan Region produce limestone powder for filler in the composition of asphalt mixture [39]It can benefit from these factories for soil The chemical composition of limestone powder ResearchGate2023年10月11日 Geotechnical investigation and stabilization of soils through limestone powder at Abbottabad, KhyberPakhtunkhwa, Pakistan: a cost effective and sustainable approachGeotechnical investigation and stabilization of soils through limestone 2024年1月2日 Several researchers have looked into how limestone powder (LP) affects concrete’s workability (Joudi et al 2012), and Lee et al found that GP has characteristics like a multiangle surface, volcanic ash activity, and a microaggregate effect They also found that with an increase in fineness value, GP can Influence of recycled concrete, marble, glass, and limestone powder
