Portland-Limestone Cement

Cement is made by grinding clinker—the main energy intensive ingredient—to a fine powder. Producers know that replacing some of the clinker in portland cement with ground limestone offers benefits, the most important being that it reduces the embodied CO2 of the cement.

Jet mill grinding of portland cement, limestone, and fly

Nov 01, 2013· When investigating the OPC/limestone, the grinding effect was more pronounced at lower w/p of 0.35 than at higher w/p of 0.50. This was due to the fact that in the lower w/p mixtures, the replacement of cement by limestone allows the remaining cement to hydrate more completely, resulting in a higher degree of hydration.

Understanding Limestone in Cement| Concrete Construction

Mar 26, 2015· {Question} My cement supplier is adding limestone to their cement. Is there anything to worry about? Will I have to reduce the fly ash content I normally use? {Answer} Recently, ASTM C150 was harmonized to meet the AASHTO M85 to allow up to 5% limestone in the cement. The history of limestone in cement is a little checkered, and as a result, there is some controversy in this decision,
