JOIN CONCRETE SCHOOL FOR FREE AT CONCRETESCHOOL.CO! ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST What happens when a concrete maturity system is built on the wrong starting temperature? Seth is joined again by Dr. Jon Belkowitz, also known as Concrete Adamus, to explain why datum temperature is one of the most important and commonly overlooked parts of the maturity method. Jon argues that assuming, ignoring, or defaulting the datum temperature can produce the wrong strength relationship. That...

JOIN THE ACADEMY! VISIT CONCRETESCHOOL.CO TO START LEARNING TODAY. ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Are we specifying air entrainment in concrete that does not need it? Seth is joined by Dr. Bruno Fong Martinez, Baker Construction’s concrete materials expert, to examine when air entrainment protects concrete and when it creates unnecessary problems. Air entrainment improves durability where concrete experiences repeated freezing, thawing, and moisture saturation. But Bruno argues...

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,...

CONCRETESCHOOL.CO ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Should we really design concrete infrastructure for 75 to 100 years? In this episode, Seth is joined by Dr. Jon Belkowitz to question one of civil engineering’s favorite ideas: the 100-year design life. Using Hoboken, New Jersey as the example, Seth and Jon talk about what happens when old infrastructure has to serve a city that no longer looks,...

We design concrete for 75 years. So why are we okay watching it fail in 12 to 24 months? That’s the uncomfortable question Seth Tandett puts on the table with Dr. Jon Belkowitz in this episode. Codes, specifications, and budgets are still written around a 50–75 year design life. But in the field, concrete surfaces are scaling, wearing, and failing in as little as a year or two. Instead of revisiting that original promise, the industry seems stuck reacting to failures instead of asking why they...

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...

Most concrete looks the way it does for one simple reason. We keep designing around the forms we know how to build. In this episode, Seth sits down with Darren Baldwin, President of PIKUS, to break down the real difference between analog formwork and digital formwork—and why that distinction quietly limits what architects, engineers, and contractors think is even possible with concrete. This is not a hype-filled “3D printing is the future” conversation. It’s a practical discussion about where...

Most people think moisture problems in concrete come from below the slab. Concrete Bob Higgins explains why that assumption keeps blowing up floors. In this episode, Bob Higgins breaks down how moisture actually moves through concrete, why liquid water and water vapor are not the same thing, and how alkalinity quietly does more damage than most people realize. We also get into why common moisture testing methods are misused, why surface damage matters more than deep readings, and how outdated s...

Most people believe the chart on the screen — Dr. Jon explains why you shouldn’t. If you’ve ever sat in a conference session staring at a chart and wondering whether you’re seeing real data or a dressed-up story, this episode is for you. Dr. Jon Belkowitz breaks down how data in the concrete industry is often stretched, normalized, cherry-picked, or misleading — and how to spot it before making decisions that affect a structure’s performance. We get into why people present data, what questions...
