PLC Equals Lower Carbon Cement
Portland Limestone Cement (PLC) offers architects and engineers a new way to think about concrete. PLC reduces CO2 impacts while still offering the resilience, durability, performance, and strength we have come to expect from concrete.
What is PLC?
PLC is manufactured with more interground limestone than traditional Portland cement. It performs just like the cement you are used to using, resulting in the same concrete you are used to having. It is the same performance with a better carbon profile.
How PLC is Made
While traditional Portland cement contains up to 5% interground limestone, PLC is made by intergrinding up to 15% limestone. This formulation reduces the amount of clinker used that is associated with energy demand and process emissions. This is how a roughly 10% reduction in emissions is achieved.
PLC is Proven and Widely Accepted
PLC is not new. It has decades of proven performance around the world. It does not require new production facilities or additional transportation impacts as it is produced with existing limestone sources and at current cement plants.
Workability:
In the concrete world, the term Workability is used to describe how easily fresh concrete can be placed, consolidated, and finished without unwanted segregation of its materials. Concrete made with PLC tends to be easier to work with to achieve lighter shades and smooth finishes.
