Concrete Logic

Seth Tandett

What is the most used manmade material on Earth? You guessed it – concrete. In each episode of Concrete Logic, we will explore one concrete-related topic with the help of industry professionals that are shaping the future of the trade. We’ll talk with suppliers, contractors, architects, engineers, specialists, and even some proponents of competing materials about their views of concrete and their vision of its future.

    EP #161: Should We Stop Designing Concrete for 100 Years?

    JOIN THE ACADEMY!! FOR A LIMITED TIME, VISIT CONCRETESCHOOL.CO FOR YOUR FREE ACCESS!! 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, moves, or functions the way it did when that infrastructure was built. The issue is not just whether the concrete lasts. The bigger question is whether the original decision still makes sense. Jon argues that the industry should stop designing only for age and start designing around use, performance, maintenance cycles, and accountability. Maybe a 20-year design life with zero maintenance is harder, and more honest, than a 100-year design life nobody is around to answer for. WHAT YOU’LL LEARN · Why Dr. Jon Belkowitz questions the 100-year design life · What Hoboken, New Jersey teaches us about old infrastructure · Why designing for time may not be the same as designing for use · The difference between design life and maintenance life · Why a 20-year, zero-maintenance target may be harder than a 100-year target · How infrastructure decisions made today can trap future generations · Why compressive strength is not enough to define concrete performance · How sensors, inspections, and data could change infrastructure maintenance · What pavement condition index means and why timing matters · Why Roman concrete is not always a fair comparison for modern infrastructure · Why Jon says we should design for decision cycles instead of age CHAPTERS (0:00) Introduction and support for the show (4:55) Rethinking 100-year design life (7:39) Why designing for time may be the wrong approach (9:57) Seth pushes back on whether we already design shorter than we admit (11:11) Hoboken as a case study (14:13) The 20-year, zero-maintenance idea (15:00) Performance, sensors, and maintenance systems (16:15) Pavement condition index and the cost of waiting (17:45) Why Roman concrete is not the right comparison (18:08) Bridge inspection and infrastructure careers (22:56) Building on top of old Hoboken infrastructure (26:14) Why predicting 100 years out is almost impossible (28:59) Final takeaways: Design for decisions, not age GUEST INFO Dr. Jon Belkowitz  Intelligent Concrete Guest link:  https://www.concretelogicpodcast.com/guests/jon-belkowitz/ CONCRETE LOGIC ACADEMY The people who understand concrete are the people who get listened to.

Learn more here: https://www.concretelogicpodcast.com/gprs   ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Is Type IL cement really the reason concrete started acting different, or did it just expose the problems we already had? Type I/II cement may be making a comeback because contractors, producers, and owners want concrete to act like concrete again. But Concrete Bob Higgins says we need to be careful. Because before Type IL showed up, the concrete industry still had scaling, dusting, cracking, bad curing, water problems, surface failures, and specs that cared more about 28-day strength than long-term durability. So if Type I/II comes back, will the problems go away? Or will we lose our favorite excuse? In this episode, Seth and Bob talk about what really changed in cement, why older concrete behaved differently, why today’s concrete may be more sensitive than the standards admit, and what the industry needs to fix before it repeats the same mistakes. Type IL may have exposed the problem. But it may not be the whole problem.   WHAT YOU’LL LEARN  · Is Type IL cement really the problem, or did it expose bad habits?  · Why Type I/II cement may be coming back  · What concrete problems existed before Type IL became common  · Why older cement was coarser, slower, and often more durable  · How finer cement changed heat, curing demand, cracking, and permeability  · Why Type I and Type III cement are closer than most people realize  · What self-desiccation means and why it matters at the concrete surface  · Why the top inch of concrete may be the weakest link  · What contractors and producers should ask before switching back to Type I/II  · Why going back to Type I/II cement does not fix bad concrete habits   CHAPTERS 00:00 Is Type IL really the problem? 04:03 Why Bob says the industry needs this conversation 06:07 What cement was like before modern concrete problems 08:17 Same 28-day strength, but more permeability 09:25 Type I vs Type III cement 13:19 Why curing may not be protecting the top inch 16:47 What self-desiccation means in plain English 18:52 Why precast concrete can have a surface problem 21:50 What to ask before switching back to Type I/II 24:07 Bob’s Type IL limestone float experiment 25:29 Why the industry cannot waste this opportunity 27:17 Next topic: are admixtures being mishandled?   GUEST INFO  Bob Higgins, Concrete Bob  Concrete chemistry consultant and returning guest on the Concrete Logic Podcast.  Guest link:  https://www.concretelogicpodcast.com/guests/robert-higgins/   CONCRETE LOGIC ACADEMY  The people who understand concrete are the people who get listened to.  Not the loudest person in the meeting.  Not the guy repeating what he heard ten years ago.  Not the person blaming every problem on the latest material change.  The person who understands the “why” behind the concrete usually has the most valuable voice in the room.  That is what Concrete Logic Academy is built for.  You get practical concrete education, PDH courses, and real-world lessons pulled from the same topics we cover on the Concrete Logic Podcast.  Cement changes.

Learn more here:  https://www.concretelogicpodcast.com/gprs ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST The concrete industry spent the last few years blaming Type IL cement for almost everything. Cracking. Scaling. Low breaks. Slow set times. Higher water demand. Now Type I/II cement may be making a comeback. So what happens when the “bad guy” leaves the room and the same concrete problems are still standing there? Rich Szecsy joins the show to explain what he is seeing in the Dallas-Fort Worth market, why cement suppliers are shifting, and why this move back to Type I/II may expose an uncomfortable truth. Maybe Type IL caused some problems. Maybe it didn’t. But concrete was never problem-free before Type IL showed up. WHAT YOU’LL LEARN Is the cement market really shifting back to Type I/II?Why did Type IL become so common after 2020?What happens when one cement type gets blamed for every concrete problem?Will cracking, scaling, low breaks, and set delays disappear?Why the producer-contractor relationship matters more than internet argumentsHow ready-mix producers may handle Type IL and Type I/II at the same timeWhy the market, not the noise, decides which cement gets usedCHAPTERS  00:00 Introduction  01:02 The big topic: Type I/II cement coming back  01:26 How to support the Concrete Logic Podcast  03:34 Rich’s view on the Type IL vs Type I/II shift  04:24 Why Type IL became more available after 2020  05:31 Rich’s 100% placement rate during the supply crunch  06:44 Concrete complaints blamed on Type IL  07:45 What happens if Type I/II returns and problems continue?  09:33 Contractors adjusting to changing cement types  10:07 Micro business needs vs macro industry needs  10:59 Past material changes that caused industry panic  11:24 Why concrete has always had variability  12:28 The old Type I vs Type II confusion  12:43 What cement suppliers are telling customers  13:05 Is the market asking for Type I/II again?  14:00 Why the market decides which cement wins  14:58 How quickly Texas shifted from Type I/II to Type IL  16:08 How ready-mix producers may handle both cement types  16:47 Submittals that allow either Type IL or Type I/II  17:29 Rich’s blunt definition of quality  18:35 Why the producer-contractor relationship matters most  19:51 Jobsite meetings, AI research, and “raspberry”  20:54 Is the Type I/II shift really happening?  21:28 Closing thoughts GUEST INFO Rich Szecsy, CEO, Big Town Concrete  https://www.concretelogicpodcast.com/guests/rich-szecsy/ CONCRETE LOGIC ACADEMY The people who understand concrete are the people who get listened to.

Click the GPRS image on the Concrete Logic Podcast website or go here: https://www.concretelogicpodcast.com/gprs ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Spring is when concrete starts telling the truth. After months of cold weather, snow, ice, rain, deicers, and freeze-thaw abuse, your existing concrete may start showing what it went through all winter. In this episode, Dr. Jon Belkowitz joins the show to talk about what to look for when the weather warms up. Scaling. Flaking. Blotchy spots. Exposed aggregate. White staining. ASR gel. Rust bleeding from cracks. All of it is concrete trying to tell you something. Some of it may be surface damage. Some of it may be a sign of a much bigger problem inside the concrete. And if you wait until the damage is obvious, you may already be late. WHAT YOU’LL LEARN Why spring and early summer act like a “lie detector” for existing concreteWhy damaged concrete often looks darker or blotchy after rainWhat scaling, flaking, and surface loss can tell you about winter damageWhy broom finish disappearance may be a warning signHow ASR cracks hold water and reveal themselves after rainWhat white staining and gel coming out of cracks may meanWhy some concrete problems cannot simply be cleaned off or sealed overHow wetting, drying, deicing salts, and outside contaminants can keep feeding deteriorationWhy extending the life of existing concrete may be one of the most practical “green” moves in constructionCHAPTERS 00:00 Introduction  02:52 What warm weather reveals about existing concrete  03:39 Concrete as a springtime lie detector  04:26 Why newer concrete may look white, blotchy, or damaged  05:22 Scaling, flaking, and lost broom finish  06:01 Why rain makes concrete damage easier to see  07:10 Why damaged concrete holds water  08:25 Rust, staining, and visible cracks  09:02 Spillways, white streaks, and concrete exudation  10:36 Alkali-carbonate reaction and internal concrete problems  11:27 What “oozing” gel from cracks means  12:43 Why cleaning the surface does not fix internal damage  13:00 Slowing deterioration versus fixing it  14:21 The practical side of reducing concrete’s carbon footprint  15:11 How ASR cracks grow and spread  16:15 ASR research and gel morphology  17:17 Protecting concrete from outside contaminants  18:21 Concrete Logic Academy and PDH reminder  19:39 Closing thoughts GUEST INFO Dr. Jon Belkowitz  Intelligent Concrete  https://www.concretelogicpodcast.com/guests/dr-jon-belkowitz/ CONCRETE LOGIC ACADEMY Most concrete problems do not show up out of nowhere.

    THIS EPISODE IS BROUGHT TO YOU BY: GPRS Before you cut, core, drill, or excavate, make sure you know what is inside the concrete. GPRS helps contractors locate rebar, conduit, post-tension cables, utilities, and other hidden hazards before they become expensive problems. Their scans help reduce hits, downtime, expenses, and keep your people safe.  Learn more here:  https://www.concretelogicpodcast.com/gprs  ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Low-carbon cement sounds good on paper. But can it actually compete in the real concrete market without subsidies, mandates, or customers paying a “green premium”? That is the question Seth gets into with Ryan Gilliam, CEO of Fortera. Ryan explains how Fortera’s approach differs from many other low-carbon cement companies by bolting onto existing cement plants, using limestone as the feedstock, and turning CO₂ back into a reactive cementitious product. This conversation gets into the hard part of low-carbon cement: economics, field performance, scaling, ready-mix adoption, policy risk, and whether these products can survive when the market stops caring about the carbon story. Ryan makes the case that the future of low-carbon cement will not be built on guilt, regulation, or good intentions. It has to perform. It has to be cost competitive. And it has to work in the field.  WHAT YOU’LL LEARN  • Why “green cement” usually makes contractors and producers assume there is a compromise  • How Fortera’s technology bolts onto existing cement plants instead of replacing them  • Why limestone loses roughly 44% of its weight as CO₂ during traditional cement production  • How Fortera claims to turn that CO₂ back into cementitious material  • Whether Fortera’s product should be thought of as an SCM, a cement replacement, or a new cement  • Why ready-mix producers are skeptical of alternative cements  • What field feedback Fortera has received on finishing, flow, pumping, set time, and cracking  • Why Ryan does not believe customers will pay large green premiums  • How policy changes could impact demand for low-carbon cement  • Why carbon capture usually struggles economically  • How Fortera’s approach differs from traditional carbon capture and storage  • What has to be true for low-carbon cement companies to scale  • Why first commercial plants are such a hard step for new cement technologies  • Why Ryan believes performance, not carbon marketing, will decide which technologies survive  CHAPTERS 00:00 Introduction to Ryan Gilliam and Fortera 03:25 Ryan’s background in materials engineering and cement research 05:20 Fortera’s approach to low-carbon cement 08:28 Is Fortera’s product an SCM or a new cement? 09:23 Blended cement use versus 100% product use 10:33 What is driving demand for low-carbon cement? 13:39 Scaling challenges for new cement technologies 15:43 Field feedback on alternative cement performance 18:58 Type IL rollout, skepticism, and contractor pushback 20:07 Policy risk and whether low-carbon demand depends on regulation 22:18 How Fortera captures CO₂ from limestone 23:07 Why the economics may work 24:41 How this differs from traditional carbon capture 25:45 What cement plants need to adopt the technology 28:07 Fortera’s history and lessons from earlier attempts 29:00 How Fortera may go to market 30:20 Ryan’s main takeaway for the concrete industry 32:09 How to contact Ryan Gilliam  GUEST INFO  Ryan Gilliam  CEO, Fortera  Profile: https://www.concretelogicpodcast.com/guests/ryan-gilliam/  CONCRETE LOGIC ACADEMY  If you work in concrete and want practical education that actually connects to the jobsite, check out Concrete Logic Academy.  This is not theory for the sake of theory.  It is concrete education built around the stuff producers, contractors, engineers, and field leaders deal with every day.  Specs.

Learn more here:  https://www.concretelogicpodcast.com/gprs ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Everyone wants concrete work done faster. But what if one of the biggest schedule killers is not the pour, the weather, or the labor shortage? What if it starts with the reinforcement choice? In this episode, Seth talks with TJ Lambert of Forta about how reinforcement decisions affect labor, sequencing, inspections, procurement, finishing, mix design, carbon reporting, and overall project speed. They discuss where fiber-reinforced concrete fits, where it does not, and why engineers, producers, and contractors need to think beyond “replace the bar and move on.” WHAT YOU’LL LEARN Why reinforcement choices can slow a concrete project down before the first truck shows upHow fibers can reduce labor, congestion, inspection steps, and field coordinationThe difference between microfibers, macro synthetic fibers, and steel fibersWhere fiber reinforcement makes sense, and where traditional rebar still belongsHow concrete producers handle fiber dosing at the plant or into the truckWhy fiber-reinforced concrete can help contractors place more mud fasterHow EPDs, LCAs, GWP targets, and Buy America requirements are showing up in reinforcement decisionsWhy finishing fiber-reinforced slabs still depends on timing, mix design, vibration, and field conditionsHow Type IL cement may affect finishing timing, saw cutting, paste, and surface performanceWhat engineers need to know about ACI 544, ACI 360, ACI 330, and ACI 318 when considering fiber designsCHAPTERS 00:00 Introduction: Can reinforcement choices kill your schedule? 04:02 What Forta does and how fiber-reinforced concrete fits 05:01 Why reinforcement choices affect schedule more than people realize 08:42 What fibers look like in the field 11:57 Matching fiber type to the right concrete application 13:26 What fiber use means for concrete producers 16:45 Fiber loading, truck mixing, and added time at the plant 17:17 How much time can contractors save by eliminating bar placement? 19:47 EPDs, GWP, and carbon reduction with fiber reinforcement 22:13 Why finishers struggle with some fiber-reinforced slabs 26:43 Type IL cement, paste, timing, and fiber finishing concerns 30:05 Fly ash, slag, mix design complexity, and owner expectations 31:54 What engineers need to understand before using fibers 35:03 TJ’s main takeaway: Start with design, not just substitution 37:06 How to contact TJ Lambert GUEST INFO TJ Lambert Sales Engineering Manager, Forta / Helix Steel Profile: https://www.concretelogicpodcast.com/guests/tj-lambert/ Forta website: https://fortacorp.com Helix Steel website: https://helixsteel.com CONCRETE LOGIC ACADEMY Concrete Logic Academy is built for people who actually work with concrete.

Learn more or request a quote here:  https://www.concretelogicpodcast.com/gprs ON THIS EPISODE OF THE CONCRETE LOGIC PODCAST Ready-mix producers are being asked for EPDs more often, especially on data center and large infrastructure projects. 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?

    EP #154: Why Concrete Is on the Critical Path for AI Data Centers

    PRESENTED BY: GPRS Construction professionals know that utilities and concrete reinforcements can cause big problems when you’re on the job. GPRS helps you avoid them. We use ground penetrating radar to detect rebar, conduit, and post tension cables before you cut, core, or drill. And our concrete scans are 99.8% accurate - we guarantee it - helping you reduce hits, downtime, expenses, and keep your people safe.

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.
