 · Portland-limestone cement (PLC) performance is controlled, to a significant extent, by limestone content and fineness. There are questions about how much fineness is needed or beneficial, with the most commonly used guidelines focused on how to achieve performance comparable to ordinary portland cement (OPC).

Portland limestone cement is a relatively new type of blended cement in the US market. Currently, there are no separate national statistics kept on portland‐limestone cement production. The LCI dataset captures 820,451 metric

In practice, portland-limestone cement is ground to a higher fineness compared to portland cement. An increase of Blaine in the range of 100cm 2 /g is necessary to compensate for the strength reduction resulting from the addition of 1% limestone. 3

OneCem® Portland Limestone Cement, a hydraulic cement for strength and durability. OneCem® creates less CO2 than traditional Portland cement. It''s a big step up for sustainability—and it makes everything you build that much stronger.

 · Portland cement is about 91 percent clinker, while PLC is just 83 percent clinker. Limestone content is up to five percent in ordinary Portland cement (OPC), but as high as 15 percent in PLC. PLC blends appear in residential, commercial and government projects. Specifiers list PLC concrete for bridges, pavements and a wide variety of structures.

 · Portland-limestone cement (PLC) has comparable performance properties to ordinary portland cement but improves the environmental performance of concrete. PLC has been used in the United States on a limited scale in accordance with ASTM C1157 for several years, but it is still considered a relatively new technology.
