EP #130: Concrete Failing with Type IL? It Might Be the Admixtures, Not the Cement
About this Episode
Everyone’s pointing fingers at Type IL cement, but what if your admixtures are the real problem?
In this episode, Dr. Jon Belkowitz returns to the Concrete Logic Podcast to challenge the one-to-one replacement myth and shine a light on the role of admixture compatibility. If your concrete is failing early—or your team is just managing problems instead of solving them—this episode is a must-listen.

If your concrete is failing early—or your team is just managing problems instead of solving them—this episode is a must-listen.
What You’ll Learn:
- Why do so many people still believe Type IL is a one-to-one replacement?
- What’s the real impact of outdated admixtures on today’s cement?
- How do compatibility tests help prevent concrete failures?
- Why are some producers thriving with Type IL while others are falling behind?
- What questions should ready-mix suppliers be asking their admixture reps?
- Are outdated specifications setting projects up to fail before they start?
- How is complacency contributing to early-age concrete failures?
