Portland-Limestone Cement

Portland-limestone cement (PLC) is a blended cement with a higher limestone content, which results in a product that works the same, measures the same, and performs the same, but with a reduction in carbon footprint of 10% on average.

Understanding Limestone in Cement| Concrete Construction

Mar 26, 2015 The added limestone in the U.S. is modern portland cement and consists of ground clinker, a source of readily soluble sulfates and functional additives. The change is that the specification adds up to 5% limestone. The biggest difference in production is that the limestone is added to the clinker blend before grinding.

Cement Wikipedia

Portland cement, the most common type of cement in general use around the world as a basic ingredient of concrete, mortar, stucco, and non-speciality grout, was developed in England in the mid 19th century, and usually originates from limestone. James Frost produced what he called "British cement" in a similar manner around the same time, but did not obtain a patent until 1822.
