Reduce Your Carbon Footprint with Blended Cements like PLC
Proven Performance. Readily Available.
Why PLC
Durable.
Resilient.
A lower carbon footprint.
Portland-limestone cement (PLC), or Type IL, is engineered with a higher limestone content than portland cement to reduce the carbon footprint of concrete by up to 10%. It performs similar to the cement you’re used to using, resulting in concrete with a better carbon profile.
Tested & Proven
PLC has been subjected to extensive research and testing by industry, both in the U.S. and elsewhere. Researchers have studied fresh properties related to placing and finishing, as well as hardened properties that relate to durability.
Proportioning Concrete Mixtures with PLC
PLC is generally designed to replace portland cement at the same cement content to result in comparable concrete performance. Start with the same amount of PLC to replace portland cement, and then test the mixture to confirm fresh and hardened properties.
Applications & Uses
Anywhere portland cement is used, blended cements like PLC can be used.
Industry Acceptance
All 50 state departments of transportation approve the use of PLC for infrastructure projects.​
