With a growing interest in sustainability, the construction industry is looking for solutions to help reduce its carbon footprint. The Portland Cement Association’s newly released Roadmap to Carbon Neutrality lays out the cement and concrete industry’s commitment to a lower carbon future. With its proven performance, portland-limestone cement, or PLC, will play a key role. This presentation explains what PLCs are, how to use and specify them, and presents results of research comparing ordinary portland cement concrete to PLC concrete, along with several examples of successful PLC projects in the U.S. over the past decade.

After this program, participants will come away with the knowledge described by these four learning objectives:

1. Understand the potential savings in CO2 footprint when using PLC to make concrete and explain how that is achieved.
2. State the replacement level and how to modify mix designs when swapping in PLC for OPC.
3. State how supplementary cementitious materials (SCMs) contents are affected by using PLC.
4. Describe how PLC affects fresh and hardened concrete properties relative to OPC concrete.
