What if the answer to today’s concrete durability and sustainability challenges isn’t new—but something we left behind decades ago? In Episode #129 of the Concrete Logic Podcast, host Seth Tandett talks with Joseph E. Thomas, Executive Director of the Natural Pozzolan Association, about a material used in the Hoover Dam and Roman aqueducts: natural pozzolans. Joseph explains how these natural pozzolans are making a quiet comeback and why they may deserve another look. What You'll Learn: - What...

What if you were told there’s better concrete out there with more limestone than what’s used in Type IL cement mixes? Sounds crazy, right? But that’s exactly what we’re exploring today with John Guynn and John Kline. In this episode, we explore ACI 211-7R and its potential to reduce cement content without sacrificing performance. Learn how adjusting particle size distribution, using admixtures, and understanding the water-cement ratio can improve workability and strength. Plus, get insights on ...

In this episode of the Concrete Logic Podcast, Dr. Jon Belkowitz and host Seth Tandett discuss the excessive costs and challenges associated with low carbon concrete, particularly Type 1L cement. They delve into the implications for the cement industry, the struggles faced by Departments of Transportation (DOTs) with new cement standards, and misconceptions surrounding blended cements. The conversation covers the shift towards performance-based design, the implications of ACI 323 on concrete pra...

In this episode of the Concrete Logic podcast, host Seth Tandett speaks with Larry Sutter, principal engineer at Sutter Engineering, about the development of standards and specifications for supplementary cementitious materials (SCMs) like fly ash and slag. They discuss the differences between standards and specifications, the role of fly ash in improving concrete durability, and the challenges of variability in materials. Larry also highlights emerging test methods for evaluating SCMs and the i...

In this episode of the Concrete Logic Podcast, Seth Tandett interviews Colin Lobo, the Executive Vice President and Division Head of Engineering at NRMCA. They delve into the differences between prescriptive and performance specifications in concrete, discussing the implications of each on responsibility, compliance, and industry practices.

In this Concrete Logic Podcast episode, Aaron Fisher discusses the importance of engaging with sustainability in the concrete industry. He highlights the need for concrete professionals to be part of the conversation and influence the rules and regulations being developed. Aaron explains how the focus on CO2 emissions has led to an oversimplification of sustainability and the need to consider other factors such as water usage, fire resistance, and durability. He emphasizes the importance of p...

In this episode of the Concrete Logic Podcast, host Seth talks to Sam Lines from ConSeal about microbial-induced concrete corrosion, particularly in the sewer system. They discuss various ways to mitigate this, including using antimicrobials and the potential consequences for failing to do so. Sam highlights the importance of designing sewer systems well, considering factors such as expected mass loss and humidity levels. He also talks about current research and potential future technologies ...

Usually in concrete construction, we think about the big things we can see - formwork, rebar, ready-mix concrete, tower cranes, trucks, excavation equipment, and laser screeds. In this episode, we will explore the benefits of thinking about concrete at a one-billionth nanoscale. Dan McCoy joins the podcast and shares his experience introducing nano-silica technology to his contracting business. Dan designs, pumps, and builds bridges with concrete. If you want to hear from a contractor t...
