What happens when the concrete industry’s “wonder dust” meets its high-tech rival? In this episode of the Concrete Logic Podcast, host Seth Tandett brings back Dan McCoy and Dr. Jon Belkowitz to challenge everything we thought we knew about silica fume. From bridge deck overlays that crack like eggshells to the real CO₂ math no one wants to talk about, the guys separate hype from chemistry and ask the only question that matters: What are we really asking this concrete to do? What You’ll Learn • What is silica fume really — and how did it end up in our concrete? • How does colloidal silica change the way concrete performs in the field? • Why bridge deck overlays using silica fume often fail before their time. • How mix design mistakes turn silica fume into a “volatile” material. • Why colloidal silica can actually cost less than silica fume. • What’s the environmental truth behind “green” cement substitutes? • Why performance specifications—not recipes—should drive concrete design. • The one ASTM document every purchaser should actually read.

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? What You’ll Learn - What the 2011 report promised vs. what the 2024 report now admits. - How carbonation, chloride ingress, admixture control, and curing show up in the latest findings. - What the project examples (PCA exposure site, Utah DOT bridges, Texas pavements, European jobs) really say. - Claimed upsides beyond CO₂: energy savings, workability, and mass concrete heat benefits. - Why PLC is less forgiving than Type I/II—and what that means on real jobs. - The big question: is PLC an innovation or a policy-driven shift?

In this episode of the Concrete Logic Podcast, Seth Tandett breaks down the 2010 “State-of-the-Art Report on Use of Limestone in Cements” that helped launch Portland Limestone Cement (PLC) into the U.S. market. You’ll hear what the report got right, what it left out, and why Europe’s cement playbook may not fit American concrete. If you're in the industry, this episode will help you question the assumptions behind the biggest cement shift in decades. Takeaways What happens to concrete strength when limestone content isn't properly optimized? Could higher limestone levels reduce your mix's sulfate resistance? How does increased limestone affect carbonation depth and long-term durability? Is PLC more likely to cause long-term shrinkage or expansion issues? Why are curing practices in Europe so different—and does it matter? How critical is mix design when using PLC instead of traditional cement? Are we relying on research we haven’t actually read or fully understood? Chapters 01:57 Exploring the 2011 State of the Art Report 04:25 Positive Aspects of Portland Limestone Cement 05:49 Cautions and Concerns with PLC 13:25 Comparative Analysis: Europe vs. US Practices 19:20 Conclusion and Importance of Research ============================= Take Your Knowledge Further – Join Concrete Logic Academy!

Most contractors think warm weather helps speed up a pour—but what if that early strength is fooling you? In this episode of the Concrete Logic Podcast, host Seth Tandett is joined again by concrete chemist Bob Higgins to break down the real effects of high temperatures on concrete strength, durability, and long-term performance. They cover new science on curing, the shocking impact of temperature on cement hydration, and why most current standards are dangerously outdated. If you’re pouring slabs in hot weather, this episode could save your project—and your reputation. What You'll Learn in This Episode: Is your summer concrete secretly sabotaging long-term strength? What actually happens to cement hydration when concrete gets too hot? Can high early strength be misleading—and even dangerous? Why is the surface of your slab the weakest link in hot weather pours?
