What if sunlight alone—not heat—was silently destroying your concrete? In this episode of the Concrete Logic Podcast, Seth Tandett and Bob Higgins uncover a groundbreaking MIT study that reveals evaporation can be driven by light, not just temperature. This discovery doesn’t just change climate models—it could explain why concrete in the field fails in ways labs never predict. From sublimation and surface chemistry to curing practices and accountability, this episode forces the industry to face a missing piece of science hiding in plain sight. What You'll Learn - Can light alone drive evaporation—and what does that mean for concrete curing? - Why does cold-weather curing produce more durable concrete? - Is sublimation the hidden culprit behind freeze–thaw damage? - How does surface relative humidity affect cement formation efficiency? - Why do laboratory tests keep producing results that don’t match the field? - Could pigmented curing compounds or internal curing be the next solution? - Are installers being unfairly blamed for failures tied to ignored science?
