Cement and Lime-1.pdf - Manufacture of Portland Cement ...

Portland cement is a fine powder, generally gray in colour. It is composed primarily of calcium silicates, calcium aluminates, and calcium ferrites. When mixed with water (hydrated), cement solidifies to an artificial rock, similar to Portland stone. A Portland stone is a yellow limestone from the Isle of Portland, in Great Britain.

What's the difference between quicklime and cement? - Quora

Both are made from limestone. Quicklime or slaked lime as it is known is heated to a high temperature until it shatters and crumbles then crushed and bagged. When water is added to this a chemical reaction begins and the mixture begins to dehydrate and reharden. Cement is created in a similar way except clay is added to the mixture.

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 reactive silica-containing compounds -- when mixed with water, they harden quickly.
