Concrete. It’s been the literal and figurative foundation of society ever since the Romans put it to large-scale use around 200 B.C.E. Even as society’s needs and wants have evolved through thousands of years, concrete’s availability, durability, strength, and long lifespan, have made it an ideal material for the built environment.
However, today these attributes come with a global concern—concrete has a large carbon footprint due to the inclusion of ordinary Portland cement (OPC), the production of which is responsible for 8% of the world’s anthropogenic CO₂ emissions. The industry has discovered a solution by replacing Type I/II OPC in mixes with Type IL Portland Limestone Cement (PLC). Doing so has the potential of reducing the carbon footprint of concrete by 10%, without compromising performance.
The criticality of pursuing greener, sustainable practices is felt throughout the building sector, from concrete producers and contractors to construction specifiers and project owners. This informative paper, PLC: Improving Sustainability in Concrete Construction, from Holcim offers insights about Type IL PLC and considerations that can help you make a smooth transition to its use. Learn about:
- PLC’s long and successful history in the field
- Sustainability and performance properties of PLC
- Performance comparisons between PLC and OPC concretes
- Key performance properties of concrete produced with Type IL PLC
