2025/09/04

Back in 2011, the industry said portland-limestone cement (PLC) came with “no significant risks.” By 2024, the updated report admits higher carbonation rates, chloride ingress concerns, admixture sensitivity, and tighter curing demands. In this solo episode, Seth lays out what actually changed between the 2011 and 2024 reports, what the case studies do—and don’t—prove, and asks the blunt question: would PLC be this widespread without the CO₂ storyline?
