What Is the Difference Between Lime & Cement? | Hunker

Lime is produced from natural limestone by burning the stone in a kiln until only quicklime -- calcium oxide -- is left behind. The quicklime is then mixed with small amounts of water to create hydrated lime, which may be included in cement or mixed with water for use as mortar. Lime hardens by slowly absorbing carbon dioxide and turning back to limestone over time. Cement consists of highly
