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.

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 INFODr. Jon Belkowitz Intelligent Concrete Website: https://www.concretelogicpodcast.com/intelligent-concrete CONCRETE LOGIC ACADEMY Got a concrete problem no one can explain?

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 futureCHAPTERS00:00 Introduction and episode overview02:40 Early methods for measuring floor flatness05:15 How superflat floors started in warehouse logistics08:40 Measuring FF, FL, and F-min floors12:00 The history of the F-number system16:30 How superflat floors were built in the 1980s22:00 Bump cutting and manual finishing methods28:30 Profilographs and corrective grinding31:00 High-tolerance random traffic floors34:00 Laser screeds and float pans change the industry37:00 Modern methods for producing flatter floors39:00 Mix design considerations for superflat slabs42:00 The future of floor flatness measurementGUESTChad White Structural Services Inc.
