How Is Concrete Made From Limestone?
To make concrete, Portland Cement (10% – 15%) and water (15% – 20%) are mixed to make a slurry. This slurry is mixed with aggregates (65% – 75%) like crushed stone, sand, and gravel. When cement comes in contact with water, a chemical reaction begins that causes the wet mix of cement, water, and aggregates to start hardening and setting ...

New approach suggests path to emissions-free cement
Ordinary Portland cement, the most widely used standard variety, is made by grinding up limestone and then cooking it with sand and clay at high heat, which is produced by burning coal. The process produces carbon dioxide in two different ways: from the burning of the coal, and from gases released from the limestone during the heating.
