JOIN THE ACADEMY! VISIT CONCRETESCHOOL.CO TO START LEARNING TODAY. ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Does exterior concrete always need entrained air to survive freezing and thawing? Seth is joined by Jason Adams, founder and CEO of MegaSlab, to challenge that long-standing practice. Jason argues that a properly designed, highly dense concrete system may limit water intrusion enough to reduce the need for entrained air. Seth presses on the risks, including mix design, workability,...

PRESENTED BY: CONCRETE LOGIC ACADEMY Practical education and ongoing development for concrete professionals at every stage of their career. Join here: https://www.concretelogicacademy.com/ EPISODE SUMMARY Thirty years ago, concrete mix designs were simpler, more prescriptive, and easier to predict. Today, they’re optimized, blended, engineered, and heavily influenced by admixtures, SCMs, and cement chemistry. In this episode, Seth talks with Jeff Slagle from Chaney Enterprises about how ready...

Concrete Is Losing on Cost. Here’s How to Take It Back. Concrete keeps getting priced out of jobs, not because it can’t compete, but because we keep doing the same things the same way. In this episode, Seth Tandett sits down with Rich Szecsy to talk about where concrete costs actually come from and why material price increases are only part of the story. They walk through how specs, local codes, labor assumptions, and risk avoidance quietly stack the deck against concrete, even when it’s the b...

Indiana just told the cement industry it won’t accept any blended cement with more than 10% limestone. That’s a first - and it’s not sitting well with the people who pushed Type IL cement in the first place. For the first time, a state DOT pushed back on Type IL cement—and the industry fired back. Indiana’s Department of Transportation says it’s protecting performance after bridge decks started scaling. The American Cement Association says the DOT’s new limits are unnecessary, confusing, and un...

What if your concrete mix could cut a data center’s power bill by 15%? In this episode of the Concrete Logic Podcast, host Seth Tandett talks with Frank Stankunas Sr., Frank Stankunas Jr., and James Cordeiro from Silverback Concrete about a concept most engineers haven’t thought about—thermal resistivity in concrete. They explain how low rho concrete helps data centers shed heat faster, take pressure off the grid, and extend the life of buried electrical infrastructure. You’ll hear how they’re...

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 if the problem isn’t your concrete, but how you run your business? In this episode of the Concrete Logic Podcast, Seth Tandett talks with Tamson Omps, Director of Operations at Thomas Concrete, about how ready-mix producers can finally take control of their margins. Tamson lays out the seven areas that make or break profitability in the ready-mix business—from equipment maintenance and driver retention to scheduling and waste management. Whether you manage a single plant or oversee a regi...

What if sunlight alone—not heat—was silently destroying your concrete? In this episode of the Concrete Logic Podcast, Seth Tandett and Bob Higgins uncover a groundbreaking MIT study that reveals evaporation can be driven by light, not just temperature. This discovery doesn’t just change climate models—it could explain why concrete in the field fails in ways labs never predict. From sublimation and surface chemistry to curing practices and accountability, this episode forces the industry to face...

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 ...

Everyone’s pointing fingers at Type IL cement, but what if your admixtures are the real problem? In this episode, Dr. Jon Belkowitz returns to the Concrete Logic Podcast to challenge the one-to-one replacement myth and shine a light on the role of admixture compatibility. If your concrete is failing early—or your team is just managing problems instead of solving them—this episode is a must-listen. What You’ll Learn: Why do so many people still believe Type IL is a one-to-one replacement? W...

What if the answer to today’s concrete durability and sustainability challenges isn’t new—but something we left behind decades ago? In Episode #129 of the Concrete Logic Podcast, host Seth Tandett talks with Joseph E. Thomas, Executive Director of the Natural Pozzolan Association, about a material used in the Hoover Dam and Roman aqueducts: natural pozzolans. Joseph explains how these natural pozzolans are making a quiet comeback and why they may deserve another look. What You'll Learn: - What...

When concrete fails, who’s really at fault—the material or the people using it? In this episode of the Concrete Logic Podcast, host Seth Tandett is joined by Dr. Jon and Rich to tackle the growing frustrations with Type 1L cement. They ask the hard questions: Is cement the problem? Are the specs off? Or is the industry just cutting corners?
