But what are EPDs? Who is asking for them? And why should a small producer care? In this episode, Seth talks with Leise Sandeman, co-founder of Pathways, about Environmental Product Declarations, life cycle assessments, carbon reporting, and how these requirements are starting to affect concrete bids. Leise explains EPDs in plain language: what data goes into them, how cement, aggregate, admixtures, water, fuel, electricity, and transportation all get measured, and why producers should not assume this is only a “green building” paperwork exercise. The big point? EPDs are becoming part of how some owners, GCs, and hyperscale data center companies compare concrete producers. And for smaller ready-mix companies, the risk is not just the carbon number. It is being left out of the bid entirely because they do not have the documentation ready. WHAT YOU’LL LEARN What is an EPD?Why are data center owners asking concrete producers for EPDs?How does a life cycle assessment connect to a concrete mix?What data does a ready-mix producer need to create an EPD?Why can two plants from the same producer have different EPD numbers?How much of a concrete EPD is driven by cement?Are owners comparing concrete producers against each other?Why might simply having an EPD help a producer win work in some markets?How could EPDs affect smaller 2-to-10-plant ready-mix operations?Why does Leise think EPDs are becoming more about business than climate messaging?CHAPTERS 00:00 - Intro and Concrete Logic Podcast support  03:15 - Who Leise Sandeman is and what Pathways does  03:52 - What is an EPD?  04:35 - Who is asking for EPDs?  05:54 - Where EPDs came from and how LCAs fit in  06:48 - Comparing concrete to other materials and other producers  07:36 - How cement and material supplier data affect EPDs  08:33 - Why EPDs involve a lot of math and manual work  09:07 - Generic EPDs vs producer-specific EPDs  10:09 - The three major data inputs for a concrete EPD  11:24 - Why utility and grid data matter  12:07 - What owners and hyperscalers compare  13:48 - How far the life cycle assessment goes  15:28 - How cement EPDs are built  16:12 - Does the EPD stop at placement?  17:16 - End-of-life questions and future standards  18:42 - Concrete’s carbon footprint vs material volume  20:29 - Why supplier choices can change the EPD number  21:21 - Why smaller producers need a simpler path  23:42 - Where EPD requirements may be heading  24:04 - Why EPD publishing is expected to grow  25:21 - Future inputs, fuels, SCMs, and supplier options  26:34 - How to contact Leise and Pathways GUEST INFO Leise Sandeman  Guest Profile:  https://www.concretelogicpodcast.com/guests/leise-sandeman/ CONCRETE LOGIC ACADEMY Tired of getting your concrete education from a PowerPoint presentation given by some guy who has probably never stepped in mud?

In this episode, Doug Mouton explains why concrete is still one of the most important materials in the data center boom, even if it is only a small slice of the total cost. He breaks down what is driving the explosion in hyperscale and AI data centers, why projects are moving into rural areas, and why concrete supply, logistics, and mix design need to be thought through much earlier than most teams are used to. This is a big-picture episode, but it gets practical fast. If you work in concrete and want to understand where the data center market is headed and what owners actually want, this one will help. WHAT YOU’LL LEARN Why data centers are growing so fast right nowWhat a data center actually is and how it worksWhy AI is pushing demand far beyond traditional cloud computingWhy more data centers are being built in rural areasHow labor, materials, and logistics get harder as projects move farther outWhy concrete becomes a critical path item even if it is a small part of total project costWhat hyperscale owners want from concrete suppliers and contractorsWhy speed, cost, and lower embodied carbon are all being pushed at the same timeWhy leaner structural designs may be the easiest way to reduce concrete useWhy concrete supply needs to be planned much earlier on gigascale projectsHow power infrastructure is creating even more demand for concreteWhat future energy storage systems could mean for the concrete industry CHAPTERS 00:00 - Intro and Doug Mouton’s background01:20 - How to support the podcast03:20 - Why concrete matters so much to data center growth05:26 - What a data center actually is06:30 - Why cloud computing changed everything08:20 - How AI is driving a second wave of data center demand09:41 - Why more data centers are moving into rural areas11:20 - Rural pushback, trucking, roads, and local disruption12:32 - Why rural projects make labor and materials even harder13:15 - What owners and developers actually want from concrete15:05 - Speed, ESG pressure, and embodied carbon goals16:05 - Why concrete procurement is still too fragmented18:00 - Why concrete suppliers need a seat at the table earlier19:02 - How leaner design can cut carbon, cost, and schedule20:13 - Seth’s skepticism on new low-carbon materials at scale21:39 - Why scale and supply chain reality still matter22:05 - Why concrete planning should start at the very beginning23:32 - How power infrastructure creates even more concrete demand24:05 - Massive towers, gravity batteries, and future energy storage ideas25:00 - Using AI to make steel and rebar design more efficient25:35 - Will data centers get smaller, denser, and stiffer?26:20 - Wrap-up and final thoughtsGUEST INFO Douglas Mouton Mouton Advisory Services https://www.concretelogicpodcast.com/guests/douglas-mouton/   CONCRETE LOGIC ACADEMY Need PDHs that are actually worth your time?   The Concrete Logic Academy is built for engineers, contractors, and concrete professionals who want practical training they can actually use - not another boring seminar that gets forgotten by tomorrow.   Use it for PDHs.

To keep your jobsite safer, visit: https://www.concretelogicpodcast.com/GPRS SUMMARY Last episode, Dr. Jon Belkowitz walked through how to build a concrete mix design on paper. 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 this slab mix  06:28 - Where moisture content and absorption values come from  08:13 - Adjusting sand weight for moisture  10:54 - Adjusting rock weight for moisture  12:05 - What free water is and why it affects your mix  13:24 - Calculating free water from the sand  14:33 - Calculating free water from the rock  15:24 - Admixture dosage explained  16:16 - Calculating admixture ounces per cubic yard  17:28 - Calculating how much water the admixture brings  18:47 - Final batch water calculation  19:34 - Final adjusted batch mix  20:38 - What happens next at the plant  21:03 - Why admixtures are mostly water  24:51 - Withholding water and adjusting slump at the plant  26:53 - How admixture dispensing systems work  29:25 - Wrap-up and what to cover next time  GUEST INFO Dr. Jon Belkowitz Intelligent Concrete Website: https://www.concretelogicpodcast.com/intelligent-concrete CONCRETE LOGIC ACADEMY Got a concrete problem no one can explain?

To keep your jobsite safer, visit https://www.concretelogicpodcast.com/GPRS SUMMARY Concrete strength gets all the attention. But what if the real driver of concrete performance isn’t strength at all? In this episode of the Concrete Logic Podcast, Bob Higgins returns to talk about alkalinity — the chemical environment inside concrete that may control moisture behavior, curing, permeability, and long-term durability. Bob explains why alkalinity is often confused with pH, why salts inside concrete can trap moisture that testing methods never see, and why modern cement chemistry may be quietly changing how concrete cures and performs. If you’ve ever wondered why concrete behaves differently today than it did decades ago, this conversation will make you think. WHAT YOU’LL LEARN · What alkalinity actually means in concrete chemistry  · Why pH and alkalinity are not the same thing · The two alkaline salts that control moisture behavior in concrete · Why salts can trap moisture that RH tests can’t detect · How high alkalinity can lead to permeable, weaker surface concrete · The difference between porosity and permeability · Why precast heat curing can change long-term durability · Why compressive strength often fails as a durability indicator · How cement kiln dust may have increased alkalinity in modern cement CHAPTERS 00:00 Introduction  02:20 What alkalinity means in concrete  03:10 Why salts control moisture behavior  07:40 Why RH probes can miss trapped moisture  10:20 Calcium hydroxide vs sodium hydroxide  14:00 Self-desiccation and modern cement chemistry  18:00 Where alkalinity in concrete comes from  23:30 Signs of high alkalinity in concrete  24:00 Why precast surfaces can be more permeable  26:00 Porosity vs permeability explained  29:00 Why compressive strength can mislead durability  31:20 Why sealers often fail long term  33:00 Alkali-silica reaction explained  35:00 Why alkalinity isn’t being studied enough  38:00 Why RH specifications often don’t make sense  39:00 Preview: additional forms of moisture in concrete   GUEST Bob Higgins Chief Scientist https://www.concretelogicpodcast.com/guests/robert-higgins/ CONCRETE LOGIC ACADEMY If you like what you’re learning on the podcast, the Concrete Logic Academy Unlimited Pro Membership is where it all comes together.

    EP #150: Most Concrete Floors Aren’t Flat Enough. Here’s Why.

    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/ Superflat concrete floors didn’t just appear overnight. They evolved through decades of trial, error, and innovation. In this episode of the Concrete Logic Podcast, Chad White from Structural Services Inc. (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 the future CHAPTERS 00:00 Introduction and episode overview 02:40 Early methods for measuring floor flatness 05:15 How superflat floors started in warehouse logistics 08:40 Measuring FF, FL, and F-min floors 12:00 The history of the F-number system 16:30 How superflat floors were built in the 1980s 22:00 Bump cutting and manual finishing methods 28:30 Profilographs and corrective grinding 31:00 High-tolerance random traffic floors 34:00 Laser screeds and float pans change the industry 37:00 Modern methods for producing flatter floors 39:00 Mix design considerations for superflat slabs 42:00 The future of floor flatness measurement GUEST Chad White  Structural Services Inc.

    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 You get the 28-day report. It’s low. Now what?   In this episode, Seth sits down with Josh Agee, Concrete Quality Assurance Manager at F.A. Wilhelm Construction, to walk through what actually happens when a cylinder comes back below strength. Who do you call first? Is it the mix? The placement? The testing company? When do you use a Swiss hammer? When do you core? And what really matters — the cylinder… or the in-place concrete? This is a practical, field-level conversation about investigating low breaks, managing risk, and protecting your project before things spiral. If you work in structural concrete, this isn’t hypothetical. It’s coming.  WHAT YOU’LL LEARN  • Why reviewing batch tickets is the first move  • Why the middle third of the truck matters when sampling  • How poor field curing can destroy cylinder results  • What most people misunderstand about testing tech responsibility  • When to use Swiss hammers and Windsor probes  • Why coring is often the final answer  • What the rolling average actually tells you  • When concrete must be removed — and when it doesn’t  • How better pre-pour meetings reduce risk  CHAPTERS 00:00 – The low break email no one wants 03:29 – Investigating batch tickets and water additions 05:26 – Why pre-pour meetings matter more than you think 08:07 – Cure box mistakes that happen all the time 13:03 – Non-destructive testing and managing risk 15:11 – Coring and what break patterns tell you 18:26 – Rolling averages and statistical outliers 21:16 – Proper sampling: the middle third rule 23:26 – How cylinders get mishandled 25:02 – Labeling errors that create chaos 26:22 – Lessons learned moving forward  GUEST INFO Josh Agee Concrete Quality Assurance Manager F.A.

    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-mix designs actually evolved over the last three decades—what changed, why it changed, and what that means for producers, engineers, and finishers working with today’s concrete. WHAT YOU’LL LEARN What ready-mix designs actually looked like in the 1990s (and why they were so prescriptive)Why SCMs like slag and fly ash were initially resisted—and how producers got buy-inHow high-range water reducers quietly changed everythingWhy performance-based specs (P2P) shifted control back to producersWhat Type IL cement changed in real-world placement and finishingWhy data centers are driving new mix demandsWhat problems the next generation of concrete still hasn’t solved CHAPTERS 00:00 – Why this episode matters 03:20 – Jeff Slagle’s path through the ready-mix business 06:10 – What mix designs looked like 30 years ago 09:50 – When SCMs actually entered the Mid-Atlantic market 11:30 – Slag vs fly ash: field realities, not theory 14:45 – Prescriptive specs vs performance-based design (P2P) 17:00 – High-range water reducers and the air-entrainment nightmare 19:30 – Aggregate blending and plant complexity 20:30 – Type IL cement and the end of “cheap” SCMs 23:40 – Finishing challenges and jobsite adaptation 26:30 – What the future might look like for concrete mixes 29:00 – Cement supply, imports, and market pressure GUEST INFO Jeff Slagle Director of Key Aggregate Accounts Chaney Enterprises Email: JSlagle@chaneyenterprises.com Website: https://www.chaneyenterprises.com   CONCRETE LOGIC PARTNERS INTELLIGENT CONCRETE Concrete not behaving the way it should?
