This episode picks up where that left off. Because a design mix is not the same thing as a batch mix. Dr. Jon breaks down the final adjustments that have to happen before that mix can actually be used in production, including moisture corrections, free water, and admixture dosages. If you have ever wondered how a mix goes from a neat set of numbers on paper to something a plant can actually batch, this episode clears it up. WHAT YOU’LL LEARN  Why a design mix is not the same as a batch mix  How aggregate moisture changes your sand and rock weights  What “free water” really means and why it matters  How moisture in the aggregates affects water-cement ratio  How to calculate the water coming from sand and stone  How admixture dosage is calculated from cement content  Why admixtures also add water to the mix  How to calculate final batch water  What the final adjusted batch mix looks like  Why contractors and engineers should understand this math even if the plant computer does it for them CHAPTERS 00:00 - Intro and how to support the show  02:15 - Why people are actually using the podcast on the job  02:36 - Concrete Logic Academy and PDHs  03:36 - Picking up where the last mix design episode ended  04:22 - What has to change to move from design mix to batch mix  05:44 - The project assumptions for

(SSI) returns to explain how the industry went from checking floors with a 10-foot straightedge to producing high-tolerance floors for robotics, automated warehouses, and high-bay storage systems.Chad has more than 40 years of experience in concrete construction, starting as a cement mason apprentice before running his own company and later becoming a senior concrete consultant with SSI. He has worked on defined-traffic superflat floors, random-traffic high-tolerance slabs, suspended slabs, and industrial floor systems across the country.We talk about how the means and methods have changed, what actually defines a “superflat” floor, and why today’s demands for automation and robotics are pushing tolerances tighter than ever.If you’ve ever wondered how contractors actually hit FF, FL, and F-min numbers, this episode explains the real-world process behind it.WHAT YOU’LL LEARN·       What actually qualifies as a superflat concrete floor·       How floors were measured before the F-number system·       Why laser screeds and float pans changed everything·       The difference between defined-traffic (F-min) and random-traffic floors·       Why robotics and automated warehouses are demanding flatter floors·       Where most grinding corrections occur on high-tolerance slabs·       Why slump consistency and placement rate matter more than exotic mix designs·       How laser scanning and real-time data could change floor flatness control in th

The core message is simple: cracks are symptoms, not root causes, and ignoring them is how durability problems turn into long-term failures.This is a practical, field-informed conversation for anyone responsible for designing, specifying, building, or maintaining concrete structures.WHAT YOU’LL LEARNWhy ASR remains one of the most misunderstood concrete durability issuesThe difference between ASR and AAR—and why the distinction mattersHow reaction-driven cracking differs from typical shrinkage or restraint crackingWhen ASR damage can accelerate faster than expectedHow ASR is identified and diagnosed in real structuresWhere current ASR testing methods work—and where they fall shortWhy prevention is still more reliable than remediationHow concrete professionals should think about cracks before they spreadCHAPTERS00:00 – Why concrete cracks should never be ignored02:11 – ASR vs. AAR: definitions and mechanisms04:50 – How ASR damages concrete over time07:47 – Identifying and diagnosing ASR in the field10:08 – Testing methods and prevention strategies13:19 – The future of ASR management in concrete structuresGUEST INFODr. Jon BelkowitzIntelligent ConcreteJon@intelligent-concrete.com

Join here: https://www.concretelogicacademy.com/ EPISODE SUMMARY If you’re building something new in this industry—mix designs, equipment, software, processes—there’s a good chance you’re creating intellectual property… without realizing it. In this episode, Seth Tandett sits down with Chen Wang, CEO of Steelike, to talk patents, trade secrets, NDAs, and the real-world decisions that decide whether you protect your advantage—or hand it to someone else. This isn’t legal theory. It’s how innovation actually gets copied in construction, why “we’ll just patent it” is usually oversimplified, and what a smart IP strategy looks like when you’re trying to build a business. WHAT YOU’LL LEARN · The difference between patents, trade secrets, and copyrights (and why it matters) · When a patent makes sense—and when it can create new headaches · How trade secrets can last forever (but only if you treat them like secrets) · What you should protect: formulations, processes, tooling, or workflow · Why NDAs are common—and why they don’t magically solve everything · How enforcement really works when someone copies your idea · The biggest misconceptions about IP in construction and engineering · How to build an IP strategy that matches your business model CHAPTERS 00:00 – Understanding intellectual property in construction 05:00 – The basics of intellectual property 08:34 – When to patent vs. keep a trade secret 10:32 – Deciding what to protect: formulations and processes 13:52 – Enforcing patents and trade secrets 15:58 – The risks and rewards of patents 18:47 – Identifying valuable trade secrets 20:05 – Protecting your ideas before sharing 23:33 – Navigating NDAs in the construction industry 25:24 – Developing an IP strategy 27:37 – Misconceptions about IP in construction GUEST INFO Chen Wang, CEO Steelike Chen@steelike.com https://steelike.com/

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’re happening. This conversation challenges some long‑held assumptions about specifications, durability, performance testing, and why compressive strength tells us almost nothing about whether concrete will actually last. This isn’t about theory. It’s about what’s showing up on real projects—and why no one seems willing to talk about the gap between what we design for and what we’re getting.WHAT YOU’LL LEARN · Why the 75‑year design life quietly disappeared from industry conversations · How concrete surfaces went from 20–30 year service expectations to failing in 12–24 months · Why compressive strength is one of the most forgiving—and misleading—tests we rely on · What durability indicators actually matter if service life is the goal · How prescriptive specs box everyone in and protect no one · Why performance‑based specifications are the only real path forward · What Peter Taylor’s work gets right about protecting the concrete surface · How warranty language misses durability altogether · Why practical field intelligence keeps getting ignoredCHAPTERS 00:00 – Intro and how to support the Concrete Logic Podcast 03:42 – Why we stopped talking about 75‑year design life 06:30 – The disconnect between specs and field performance 08:59 – Why compressive strength doesn’t equal durability 12:07 – The industry’s reliance on paper over field reality 14:34 – Why specifications need to change 15:22 – Prescription vs performance‑based specs 19:12 – What should actually be specified for durability 21:28 – Using performance tests to enforce accountability 25:22 – Warranty periods and real‑world consequences 28:07 – The concrete surface a

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 better material. This isn’t a theoretical discussion. It’s a practical look at what contractors, engineers, and producers can question, change, and push back on if they actually want concrete to stay competitive. WHAT YOU’LL LEARN·       Why concrete keeps losing bids to steel and other materials·       How self-compacting concrete can cut labor without cutting performance·       Where specifications quietly drive cost more than material prices·       How local codes create massive cost disparities for the same building·       Why fear of sharing ideas slows innovation across the industry·       How small, incremental changes can unlock real savings·       Why understanding the full contractual chain matters more than mix price·       What questions teams should be asking earlier to avoid cost traps CHAPTERS00:00 – Intro and how to support the Concrete Logic Podcast02:36 – Why concrete is struggling to compete on cost05:32 – Self-compacting concrete and labor reduction08:18 – How specifications quietly drive cost10:55 – Engineering challenges baked into specs13:44 – Local codes and why the same building costs more in different cities16:31 – The industry’s fear of sharing ideas18:58 – Incremental changes that actually move the needle21:32 – Local regulations and hidden cost multipliers23:56 – Asking better questions earlier GUEST INFORich SzecsyBio: https://www.concretelogicpodcast.com/guests/

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 digital formwork actually works, where it absolutely doesn’t, and why architectural concrete—not structure—is where this technology earns its keep.  WHAT YOU’LL LEARN • What “analog vs. digital formwork” really means in construction terms • When digital formwork beats precast on cost, logistics, and constructability • How curves, grade changes, and non-repeatable geometry break traditional forms • Why lack of data (and testing) still blocks structural adoption • Why architects keep designing square stuff when they don’t have to  CHAPTERS 00:00 – Intro and how to support the Concrete Logic Podcast 02:30 – Analog vs. digital formwork explained 04:10 – Is this just 3D concrete printing? 05:40 – When digital formwork makes economic sense 07:10 – Grade changes, curves, and non-repeatable geometry 09:20 – Testing, engineering, and the structural data gap 14:40 – Remodels, access constraints, and why lightweight matters 16:05 – Leave-in-place printed formwork (and why it’s not the focus) 19:30 – Digital concrete + millwork integration 21:20 – How to reach Darren / PIKUS  GUEST INFO Darren Baldwin PIKUS https://www.concretelogicpodcast.com/guests/darren-baldwin/  INTELLIGENT CONCRETE Concrete not behaving the way it should? At Intelligent Concrete, Dr. Jon Belkowitz and his team combine lab-level testing with real-world field experience to get to the root of performance issues, not just the symptoms. If you want data you can trust and answers you can use, learn more at

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 standards keep throwing contractors under the bus.If you’ve ever wondered why floors fail even when the numbers “look fine,” this one connects the dots.What You’ll Learn·       Why moisture in concrete is not just “moisture”·       The difference between liquid water, water vapor, and chemically bound moisture·       Why relative humidity testing is often misunderstood — and misapplied·       How alkalinity concentrates at the surface and drives real damage·       Why many moisture problems come from the top, not the soil·       What self-desiccation is and why you can’t fix it once it happens·       How material changes in cement quietly broke old assumptions·       Why contractors keep getting blamed for problems they didn’t cause Chapters00:00 – Why Moisture in Concrete Is Misunderstood 01:15 – The Different Forms of Moisture That Matter 03:30 – Why the Center of Concrete Often Doesn’t Dry 06:40 – The Problem With RH Probes and Surface Damage 10:30 – Why Cement Chemistry Changed the Rules 12:30 – What Alkalinity Really Is (and Why pH Misses the Point) 15:45 – Why New Cements Can Self-Desiccate 18:45 – Irreversible Damage From Heat and Chemistry 21:45 – Vapor Barriers, Curling, and Old Assumptions 24:30 – Why Most Moisture Comes From the Surface 28:45 – The Stack Effect Explained 31:30 – Why RH Numbers Don’t Match Real Failures 35:45 – What Needs to Change Going Forward 39:20 – Final ThoughtsGuest InfoName: Bob Higgins Email: rcconsulting.higgins@gmail.com Webpage

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 unscientific. So, who’s right—and what does it mean for the rest of the country’s concrete?

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 testing mixes that hit rho values in the 20s, why quality control is everything, and why engineers need to stop “copying and pasting” specs from old jobs. By the end, you’ll see why thermal resistivity may be the next big efficiency play in the world’s fastest-growing utility - data. What You’ll Learn • What thermal resistivity (rho) actually measures in concrete. • How low rho concrete reduces power bills and protects the grid. • Why inconsistent mixes can cause “thermal runaway” in cables. • How soil type and aggregate selection affect heat dissipation. • What testing and verification look like for low rho concrete. • Why some engineers are still unaware of rho’s importance. • How Silverback’s “Game Changer” mix is redefining performance. • What collaboration between engineers and contractors could unlock next.

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.
