RESPONSE OF PORTLAND LIMESTONE CEMENT CONCRETE

PDF Response of Portland Limestone Cement Concrete to High

General use limestone (GUL) cement with 11.3% limestone powder content, which meets the requirements of the CAN/CSA-A3001 standard (CSA 2019), was used as the main component of the binder. General Use (GU) cement, which represents typical concrete pavements cement in North America, was also used as a reference.

New approach suggests path to emissions-free cement | MIT

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.
