Portland-Limestone Cement National Precast Concrete

2014-6-2  ASTM C595 and AASHTO M240 were revised in 2012 to define portland-limestone cements with between 5% and 15% limestone by mass. 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

Portland Limestone Cement Michigan Concrete

2022-6-18  Portland-limestone cement, or PLC, is engineered with a higher limestone content than portland cement to reduce the carbon footprint of concrete by about 10%. It performs just like the cement you’re used to using, resulting in the same concrete you’re used to having. The same specifications, the same mix design, now with a better carbon profile.

How is concrete made from limestone? Shelly Company

2014-1-29  To make Portland cement—the most common type of cement—powdered limestone is heated in a rotary kiln. As a source of calcium, it joins with powdered clay to produce a product called clinker, which is then ground with a source of sulfate, like gypsum. It is mixed with water, sand and crushed rock to create concrete.
