Portland cement is a successor to a hydraulic lime that was first developed by John Smeaton in 1756 when he was called in to erect the Eddystone Lighthouse off the coast of Plymouth, Devon, England. The next development, taking place about 1800 in England and France, was a material obtained by burning nodules of clayey limestone.

Limestone powder is injected after the coal is burned, typically at the top of the boiler. The sulfur dioxide is formed when the sulfur contained in the coal (it is a contaminant in all coal) burns in the combustion chamber of the boiler. The sulfur dioxide bonds with the limestone to form a particulate; it believe that is CaSO3.

When limestone/chalk (calcium carbonate) is burnt in the kiln it turns into quicklime (calcium oxide) and releases carbon dioxide. Water can be added to quicklime/burnt lime to produce hydrated lime (calcium hydroxide). Over the lifetime of lime products, carbon dioxide is gradually re-absorbed by lime from the air, which is known as recarbonation.
