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 that could help protect concrete from this type of corrosion. Takeaways 1. Understand the concept and negative impacts of microbial-induced corrosion on concrete used in sewer systems. 2. Learn about mitigation strategies such as antimicrobials and plastic liners to reduce concrete corrosion. 3. Get introduced to ongoing research and projects to create mitigation methods for microbial-induced corrosion. 4. Discover the importance of factors including oxygen levels, sulfur presence, and relative humidity in the corrosion process. 5. Explore the potential of enhancing concrete's resistance to corrosion through quality improvements and the use of substances like antimicrobials.
