Welcome to the Concrete Podcast—where concrete finishers, engineers, GCs, ready mix producers, researchers, innovators, and DOT officials come together to share real conversations about materials, methods, and the challenges we’re solving across the concrete industry.

In Episode 9, Joe Shetterley and Joel Cookston take on one of the most controversial stories in the cement industry: the Lafarge terrorism financing case. The conversation goes beyond the headline and asks a larger question for the concrete industry:
What happens when profit becomes more important than people?

This episode begins with a discussion about Lafarge, one of the world’s largest cement companies, and the legal fallout tied to its operations in Syria.
According to public legal reports, Lafarge and its Syrian subsidiary admitted in the United States to conspiring to provide material support to foreign terrorist organizations. More recently, French court proceedings brought renewed attention to the case and the decisions made by executives during that period.
For Joe and Joel, the point of this episode is not just to revisit a corporate scandal. It is to use that case as a starting point for a much broader conversation about accountability, trust, and what happens when decisions made far upstream affect the people doing the work in the field.
The episode asks whether the concrete industry is doing enough to protect the contractors, finishers, producers, and crews who are expected to deliver durable concrete under changing material conditions.
The Lafarge case raises difficult questions about corporate priorities.
In the episode, Joe and Joel discuss how business decisions made at the corporate level can have consequences that extend far beyond revenue, production, and shareholder value. When companies are willing to make decisions that protect operations and profits under extreme circumstances, it forces the industry to ask harder questions about responsibility.
That does not mean every cement company should be blamed for the actions of one company. Joe and Joel make it clear that the goal is not to make a blanket statement about the entire industry.
Instead, the episode uses the Lafarge case to ask a larger question:
When major material decisions are made, who carries the risk?
For many contractors and finishers, the answer often feels obvious. When materials change, specifications shift, or field performance becomes harder to control, the people placing and finishing the concrete are often the ones left answering for the results.
A major theme in this episode is trust.
Joe and Joel talk about how contractors, general contractors, finishers, and producers are often expected to trust that material changes have been properly researched, communicated, and supported before they reach the jobsite.
That trust becomes harder to maintain when field crews are dealing with performance issues they do not fully control.
The episode connects this concern to the current conversation around Type 1L cement, sustainability, and lower-carbon concrete. Joe and Joel are not arguing that Type 1L cement cannot work. In fact, they acknowledge that Type 1L can be a good material when the mix, timing, finishing process, and field execution are understood.
The frustration comes from how quickly the industry has had to adapt, and how much of that burden appears to fall on the people in the field.

The Type 1L discussion in this episode centers on one main issue: field performance.
Joe and Joel discuss how contractors are seeing problems such as scaling, delamination, crazing, inconsistent behavior, shorter finishing windows, and confusion around what has changed in the mix.
The concern is not just that materials are changing. The concern is that many field teams were not given enough practical guidance on how those changes affect placement, finishing, curing, timing, water demand, admixtures, and surface behavior.
The episode also questions whether sustainability messaging has always been matched with enough field education.
Lower-carbon concrete is an important industry goal. But Joe and Joel argue that sustainability cannot be judged only by the cement content or the carbon reduction claim. If concrete has to be repaired, removed, replaced, or defended through callbacks and disputes, then the real-world sustainability picture becomes more complicated.
For them, the question is not whether the industry should innovate. The question is whether innovation is being introduced with enough transparency, testing, education, and support for the people who have to make it work.
Joe speaks directly from the perspective of a finisher. He explains that finishers are often the last people in the chain, but they are the first ones blamed when something goes wrong at the surface.
The episode discusses how the industry can become too focused on strength numbers while overlooking other performance concerns. Concrete may meet compressive strength requirements, but contractors still have to deal with surface durability, finishing behavior, timing, shrinkage, scaling, delamination, and long-term serviceability.
That is where Joe and Joel believe the conversation needs to change.
Instead of placing the burden only on the finisher, the industry needs to look at the whole system: cement chemistry, mix design, aggregate moisture, water, admixtures, batching practices, curing methods, weather, timing, and jobsite execution.
The episode does not stop at criticism. Joe and Joel also discuss practical ways contractors and finishers can start protecting themselves in the field.
One major point is verification. Joe encourages finishers and contractors not to assume the mix will behave the way older materials behaved. Instead, they need to ask better questions, review the mix, understand the water, and pay close attention to how much admixture is being used.
The episode also discusses the importance of timing. With Type 1L cement and today’s mix designs, the finishing window may shift. Crews may need to pay closer attention to pour timing, temperature, humidity, evaporation, bleed behavior, water reducers, accelerators, curing methods, and the surface condition during finishing.
Joe also emphasizes that there is no single blanket fix for every job. The right answer depends on the mix, the conditions, the contractor, and the performance goal.
For E5, this episode connects directly to the company’s larger mission: helping the industry adapt to changing concrete materials with better information, better testing, and practical field support.
Joe and Joel discuss E5’s work with nano silica technology and how E5 has focused on understanding how new cement systems behave in real placements. The conversation touches on products such as Miracle Aid and Shield as tools that may help contractors manage surface moisture, finishing support, and field conditions when used appropriately.
The larger point is not that one product solves every problem.
The point is that contractors need support, testing, and solutions that are built around what is actually happening in the field. E5’s position in this conversation is that better concrete starts with better communication between the people designing the mix, producing it, placing it, finishing it, and specifying it.

Episode 9 is a hard conversation, but it is also an important one.
The Lafarge case raises serious questions about corporate accountability. The Type 1L discussion raises practical questions about material changes, field performance, and who carries the risk when those changes are not clearly communicated.
For Joe and Joel, the message is simple: the industry needs more honesty, more transparency, and more support for the people doing the work.
Concrete is not built in a boardroom. It is placed, finished, cured, tested, repaired, and lived with in the real world. If the industry wants stronger, more durable, more sustainable concrete, then the people closest to the work need to be part of the conversation.
