Video Summary

The webinar titled "Understanding Portland Limestone Cement's Role in Precast Pre-Stressed Applications for a Lower Footprint" was presented by Claire Noacell, Technical Service Engineer for Lehigh Cement, and Jay Witt, Technical Service Engineer for Lehigh Cement. The webinar discussed the use of Portland Limestone Cement (PLC) in precast and pre-stressed applications to reduce the carbon footprint of concrete. The presenters discussed the motivation behind using low embodied carbon cement, the technical advantages of PLC, and its impact on daily production. They highlighted strategies to increase efficiency and reduce embodied carbon, such as optimizing aggregate gradations and using supplementary cementitious materials (SCMs). The presenters also mentioned the potential for adaptive reuse and modular construction in precast applications. The webinar included graphs and data showing the strength and performance of PLC compared to traditional cement. The presenters also addressed questions from attendees regarding sulfate resistance, the use of PLC in ultra-high performance concrete, Blaine values, and the potential for a type 3L cement. Overall, the webinar provided valuable insights into the use of PLC in precast pre-stressed applications for a lower carbon footprint.
